Vauxhall Astra H: Installing Eonon D510* series headunit


Disclaimer:
This is written for information purposes only. I take no responsibility for any damage that may be caused by following the instructions written in this guide.

Eonon make some great, budget headunits that are packed with almost every feature you could want… and recently, they have started to add some new models to their range made specifically for the current generation of Vauxhall/Opel vehicles. They are designed to fit the car without requiring any modification or silly adapters, and they work perfectly with the car with minimal effort required to install it, compared to most headunits. The first time installation took me roughly 45 minutes with no assistance from anyone else.

For more information on these headunits, please click the links below. The only difference between the models is the facia colour.

Eonon D5103 (Charcoal Grey)
Eonon D5107 (Matt Chrome/Silver)
Eonon D5108 (Piano Black)

So, onto the fitting!

First up, we need to remove the old stereo. You can use a coat hanger or some nails, but trust me, I tried it and it’s not easy. You’re much better off buying the keys made to do the job, they’re only a fiver from Halfords. Click here to buy. Now I’ve written this guide about 3 months after buying the unit, so obviously I’m not removing the original stereo in the picture, but the process is identical for the standard CD30 🙂

Simply insert the keys into the 4 holes on the fascia until they click into position, then pull and the unit will come out:

Note Be aware that your standard head unit is paired to the display screen in the centre. This is a security feature that means you don’t need to enter a code to access the radio if it ever gets removed or the battery dies, but at the same time, you cannot fit it to any other car unless you take the original screen with it. If you’re planning on keeping your original display (which I’m assuming you are) but planning on selling on the old stereo, you must have it “divorced” from the car. This can be done via a Tech2 or VAUXCOM device. Any Vauxhall main dealer should be able to do this, if not, there are approved traders on Astra Owners Network scattered around the country who will be able to assist 🙂

Now that the stereo is out, we need to remove the glovebox. This will assist with cable management later on during the installation process, but to give yourself a bit of space, it’s best to do it now. To do this, open up the glove box and you’ll see 4 screws, as labelled on the below photo.

These screws are a T20 torx size. Undo these 4 screws and put them somewhere safe so you don’t lose them (I’ve got a habit of losing these screws!) Once they’re out, give the glovebox a sharp tug and it’ll come straight out:

Make sure the glovebox is closed so that the light goes out, and then take off the plug from the light. This will completely release the glovebox and you can put it to one side until we’ve completed the installation

So now, you can grab all the cables that came with the Eonon. The first set of cables I’ve attached int he picture below deals with all the extra inputs for things like speakers, reversing cameras, aux inputs, etc. This block of cables does not affect the unit at all if it’s not connected, but you obviously won’t be able to use any of those features. To start with, I didn’t bother and it made fitting the unit a lot easier, but I then wanted to make use of the aux-in feature and will soon be buying a reversing camera which will need to be fitted here as well… So if you don’t need it, don’t fit it…

The next thing we’ll hook up is the main connector block. This is required for the unit to work. It deals with the speakers, all the power and the steering controls. The little red plastic box is a CANBUS decoder which allows it to talk to the rest of the car, thus allowing the steering wheel controls to work, and from what I can work out, it means it is able to write text to the centre display, although I’ve only ever seen it say “WELCOME!!!!”, and it seems a bit random how it does it…

This has one large quadlock on one end, which connects to the standard Vauxhall loom, and then it has two smaller blocks and 3 loose cables. The two smaller blocks connect to their corresponding sockets on the back of the head unit. They’re pretty obvious where they go.

The BRAKE cable should be connected to the handbrake so that it will turn off the screen when the handbrake is off while playing DVDs so that it doesn’t distract the driver… It can be wired up to an earth point to make it think the handbrake is permanently on… but even better than that, you can just not bother connecting it, and then turn off BRAKE DETECT in the head unit settings and it will completely ignore this cable.

The AMP cable should be used as a remote turn-on for an external amplifier, so if you don’t have one, then don’t worry about this.

The ANT-C cable is a bit of a tricky one. I’ve not yet completely worked this one out. I know it is for the aerial amplifier, and without it being connected, my FM radio signal is pants… The problem I’ve found so far though is that the Astra does have an aerial amplifier, but the connection for it on the back of my CD30 goes to a blank pin on the wiring loom, which would explain why this is loose and not going to the quadlock. Problem is, so far I’ve not found anywhere to connect it to, and I know a few other members on Astra Owners Network have had the same problem… It has been suggested by a member to discard the aerial adapter that comes with the unit and to buy one of these (click me) adapters, then connect it to the blue cable on the adapter… I’ve not tried it yet as I’m a cheapskate, but it may be worth a go.

So we should now be looking like this:

Next up, we will connect the GPS antenna. There is a gold and white connector between the aerial socket and the socket for all the aux-cables that is labelled GPS ANT. It’s a simple screw on coax connection so really simple to do. The GPS antenna that is supplied has a magnetic base plate, and running across the back of the dash behind the glovebox is a big metal pole. I’ve stuck the magnetic side to this pole, then run the cable through the side of the centre console into the stereo area, then conneted it to the head unit. Really simply to do:

If you want to use the USB connection or add anything to your aux block, this is probably the time to do it now. You can see the USB socket is next to the aux block.

Now we’re going to connect the stereo up to the car. So this is the quadlock that comes as standard on the car. As you can see, it’s designed in such a way that it’ll only go on one way, so you simply cannot get it wrong.

This connects to the big block on the Eonon’s loom:

Now we will connect up the aerial. The bigger end of the adapter that comes with the unit goes into the big circular socket next to the GPS antenna connection. The smaller end connects up to the white cable that is attached to the quadlock loom:

Now that is everything connected! All we need to do now is to fit the unit into the dashboard… which is the hardest part of the installation. Reason being, we now have to fit all this cable:

Into this small space:

This is where having the glovebox out comes in handy, as to the left hand side of the centre console, there is a big gap that you can access from the side of the stereo and the side of the glovebox. This is the perfect place to try and house as much cabling as possible. This is the gap:

If you’re careful enough, you can feed the majority of the cables through here and try to keep them nice and neat. This will give you a lot more space behind the unit, so you’ll find it’ll fit much flusher with less effort. If you don’t feed the cables round here, you’ll find you’re going to have a very, very hard time getting it to sit flush with the dash. As you can see here though, the cables do fit nice and tidily:

And the finished product! 🙂

      All photos taken from inside an ’05 Astra 😉

      These will fit all Astra H, Antara, Corsa C, Corsa D, Vectra C & Zafira B… with potential for a few other models. I think it might also fit the Meriva A. 🙂

      The furthest I got with this was buying the Connects2 aerial adapter from a seller on eBay and hooking the blue cable on the adapter to the ANT-C cable on the head unit. This seems to have made [i]some[/i] difference, but hardly anything worth shouting about 🙁

      It has popped up in a discussion on Astra Owners Network again last night where someone has mentioned that they bought an aerial amplifier and used the spare live attached to the 12v socket loom to power it. I know this exists on an Astra, not sure on any other Vauxhall/Opel. I will take a look myself as apparently it only cost a tenner and made an unbelievable difference. I’ll update with my findings 🙂

      Hi. I’m not too sure to be honest. I can’t say I’ve seen what the loom in the Meriva looks like. If it isn’t the standard quad lock as shown from the Astra H, then I don’t think there is an adapter available for this 🙁

      Hi,

      As mine is an early Eonon unit, I get the time, ambient temperature and trip computer display. Depending on how it feels, sometimes it’ll display a blank line in the middle where the stereo display would normally be, other times it’ll display the name of the trip function currently displaying…

      I have installed a couple of units for other Astra Owners Network members though and it appears at some point during their development, there was what I can only assume is a software update, as the hardware looks the same, but the newer ones seem to be able to firstly change the startup logo, but more importantly are able to display more information on the BID. From what I can remember of when I installed Ian’s, most functions will say “ ON”, so for example when using the sat nav, it says “GPS ON”. The FM/AM tuner will display the current frequency, but unfortunately not the RDS name. CD’s will display track number and position, but unfortunately doesn’t support CD Text like the CD30 does.

      I’m convinced it is a software update, but as yet, I’ve not been able to work out how to extract and deploy software directly to these units without abusing the sat nav software to run non-sat nav software within WindowsCE… but to be honest, it hasn’t bothered me enough to put a huge amount of effort into working it out. If I do, I’ll rip a copy of Ian’s D5108ZE software and try to deploy it to my D5108E and see what happens. I’ll be sure to update it if I get it working 🙂

      Hope that helps (Y)

    Hi,

    I have a astra h sxi 5dr with the standard CD30 and TID. I am thinking of upgrading to an d5107e next month, also want to change the dull TID. If i buy a divorced BID can i just use this with the eonon. Or does it need to be coded again? If not, will board computer function work??

    Many thanks,
    R

      Hi,

      I’ve never personally fiddled around with changing screens as I never got around to upgrading my BID to a CID, but my understanding is that for a screen to work, it has to be coded to something. It doesn’t matter if that something is actually installed in the car, but it needs to have something to pair up to…

      So I believe you need to divorce the TID from your CD30, pair the BID to the CD30, then install the Eonon.

      The trip computer on the BID will work with the Eonon unit. It is controlled using the control wheel on the left of the steering wheel. Press it in to enter the menu, then use the wheel up and down to scroll through the menu. As long as it is activate when you install it, should be fine. I believe the screens bring their configuration with them, so if I were to take the BID out of my 1.9 SRi with trip and check enabled and install it into your SXi, it should keep the trip and check configuration… The only problem would be if it gets different readouts for the engine. You’d need to check up on this. That is my understanding anyway, it may not be 100% correct. Someone like stampede or pecky on Astra Owners Network will be able to confirm 🙂

      Cheers,
      Mike 🙂

    Hi thanks for the great write up I’m now considering buying this unit fo my 06 Astra. Couple of questions. Did you ever manage to sort your radio recception issues? Do the steering wheel controls work ok?

    Also you mention if your going to sell the CD30 you have to get it deregistered, if your not going to do this, will the Eonon just work with the old display without needing to be de-paired by Vauxhall?

      Sorry one other thing, I’m thinking about running the 3.5 auxilary cable into the glove compartment, is this easy enough to do without having to drill holes in the side of it?

      Hi,

      In the end, I fitted a Connects2 adapter with an aerial amplifier and it marginally improved it, but it was never perfect. It didn’t overly bother me though as the station I listen to is available on FM and AM so I could still receive it wherever I went… Unfortunately the car is now a write off, I’ve taken the unit out and I’m selling it so I don’t think I’ll ever get to the bottom of the signal issue… It wasn’t terrible though 🙂

      Steering wheel controls work fine straight out the box.

      Yes, if you don’t plan on doing anything with the CD30, then everything will be fine. I didn’t divorce mine before I removed it and I never had any issues. The screen and Eonon were both fine.

      Running a 3.5 cable through to the glovebox depends on whether you have the glovebox aircon cooling thingy-ma-bobby. When you open the glovebox, in the top right corner at the front, you’ll see a circular hole. If there is a switch here, then you’ll need to drill the glovebox unfortunately. If there is just a hole here with no switches, then this is perfect for running any cables into. For a brief period, I had the 3.5 jack, USB cable and iPod cable all running through here until I found better places to put them 🙂

      Cheers,
      Mike

    Hi i have installed this and then have tried to install a reversing camera but my sat nav has stopped working and then the camera will only work when car is turned off. When i start the car the camera feed is inturupted and i lose the picture. Please can you help. Many thanks Andy

      I can’t say I’ve ever heard of the sat nav stop working… What actually happens and what sat nav software do you have installed?

      The loss of signal from the camera sounds like a bad earth or the CANBUS is cutting it out.

      Thanks,

    Hi, I have just bought a 2012 astra van sportive, as its the older astra shape can i just buy the Eonon D5107E for direct replacement of the CD30? Would all the steering controls work etc? As far as i can see the guide you have done here, from the pics your car looks the same as my van inside, steering wheel etc..

    many thanks

      Hi, a 2012 Astra van will be an Astra H, so yes, it’ll all fit directly with no problems. Steering wheel controls will work no problems. From memory, the default functions aren’t identical to the CD30, but most of them are the same. Volume control and the skip track does exactly the same. On the other side of the wheel, the trip computer scroll wheel will continue to control the trip computer. I think the other two buttons change the source and mute the stereo.

      There is a function on the Eonon to change the function of the controls, but I’ve never managed to get this to work. I’ve never been bothered enough to try and get it to work though…

      Cheers,
      Mike 🙂

    I’ve just bought an a-sure ovg which is essentially identical to this head unit. Nice write up there mate, although I went to install mine last night and there was 2 main problems. Firstly it’s losing all its settings and radio stations every time I switch it off. And secondly it’s not lighting up, apart from the src button.

    I’ve put this down to the acc and ill wires on the canbus decoder, so I’m guessing ill have to cut them off and hard wire them in? Although it did say this unit is plug and play in a corsa c

    Also my canbus decoder says Astra / Zafira on it. Are these models the same canbus wise, or do I have the wrong decoder?

    Regards

      No idea about the CANBUS decoder to be honest. I’ve only ever dealt with the Astras. I know the Zafira is heavily based on the Astra, so that’ll be why that is mentioned… but not sure about the Corsa.

      As for the not storing radio settings and the likes, are there two bullet connectors? One yellow cable and one red cable? If so, swap these around (Red -> Yellow and Yellow -> Red). I can’t remember exactly what these do, something like switched and ignition live… on most cars, the colours match, but for some reason Vauxhall and I think I heard Citroen and someone else, you have to swap these over for it to work properly… If you don’t have those, then I’m not sure. I think these are usually part of the ISO loom block.

    Hi,

    I have Astra GTC H, 2008 1,9 TDI (CDC 40 Opera) and I bought similar product from Sharing Digital. I was in China and I bought 2 sets. One for me and another for my friend. He has 2008 Vectra 1.9 TDI (DVD 90 NAVI). I bought these because we wanted aux-in and more options (rear camera).

    We installed these multimedia systems to our cars. I even bought high quality Sony rear cameras. After that we had many problems:
    1. Wheel buttons stopped working on the left side. Both cars have same problems.
    2. Radio signal was quite weak if you go outside of city. Both cars same problems. Original radios did not have this problem. We also did double check of connections.
    3. You can not change time/date anymore on the display (etc summer time).
    4. We put back our original systems but wheel buttons still did not work. Opel dealer tested many hours and changed wires but they thought that we beed to change CIM block or something. It is quite expensive.
    5. What we also did not like: Radio does not turn off when I turned off the engine and open left door. Original radio turned off itself.

    We tried to contact Chinese but they coudl not help us. So much support!

      Hi,

      Not sure on the steering wheel buttons issue. I know there is a section in the settings menu where you can manually set what each button on the steering wheel does, but I couldn’t ever get this to work on mine, so not sure if this will help at all. Even though they may work with the standard headunit, have you tried another set of steering wheel controls to eliminate whether the controls are at fault? I don’t think they are, but it’s worth trying.

      Radio signal unfortunately is bad on these units. The CD30 unit either has an aerial amplifier built on, or something on the loom is required to power the amplifier which isn’t on the Eonon loom. I’m assuming it’s the CD30 that had the amplifier built in, as when I sold my Astra for parts, I stripped the complete interior and didn’t come across a separate amplifier unit. I did find buying an “amplified” aerial adapter helped a little. It had a silver block in the middle and a blue wire. Connected the blue wire to the “ANT-C” cable on the Eonon to power it and it helped a little, but didn’t make enough significant difference. I gave up in the end and just lived with having poor radio signal.

      I don’t know if this works for the Vectra as well, but you can definitely change the date & time on the Astra H. See this video I made on YouTube a while back after I had a mess around and stumbled across the setting. It’s under “Settings”/”Help”/”Info”. http://nimraynn.co.uk/how-to-change-astra-clock-display-using-eonon-d5108-head-unit/

      The radio should turn off. I’m not 100% sure, but I think you still have the “Ign. Logic” setting in the car’s settings menu that could change this. Again, see the video above for changing the date & time. The same method should allow you to find the “Ign. Logic” setting. Mine always turned off whenever I took the key out the ignition, but it was delayed a few seconds compared to all other electronics.

      The speaker setup is also very strange. The CDC40 Opera does come with a centre speaker as part of the “premium speaker” package. I only had a CD30 in my Astra so I didn’t have this so didn’t experience it, but it may be worth checking the audio settings on the headunit itself to see if this makes any difference. Sounds like the pre-amp doesn’t know where to send the audio properly.

      Hope that helps 🙂

    I forgot to mention one more important thing. Original radio sent out the sound to side speakers but this chinese sent everything to middle speaker. I even did not know that my car had middle speaker in my car 🙂 But this problem was only in my car not in my friends car. He had everything ok.
