Hi all

Grabbed a 1.4 2009 C3 yesterday to tide me over as my other car broke. The radio didn’t work so I checked the wiring behind, it’s an aftermarket.

Some wires had come loose. So I connected them and managed to get the stereo on. However it’s semi broken. Obviously I noticed that my display doesn’t really work apart from flashing a date and time. Until I connected this up it just shown the range on that screen nothing else. Obviously the stalk doesn’t work with this radio.

Generally I only listen to talkSPORT anyway, but can’t with this. I would rather try and get my screen working, not sure if I can get this working with additional leads or a canbus decoder like my old Vauxhall with an aftermarket.

As FB has advised I couldn’t just use another C3 stereo as it needs to be married to the car, would I need that stereo to be unmarried to be able to marry to my car? Would I need both codes? (One from the donor and my code) to pair it? I know I’ll need software to code it like i had with my Vauxhall (opcom).

I suppose if I can get that screen working with a connector I could get a cheap aftermarket for the radio. The wiring behind the radio at the moment is so messy. Isoplug into splitter which then feeds slimkey device and another adapter into stereo.

Or is another solution another OEM screen and radio from a donor and plug and play? As I assume they will be married together (you could do that in Vauxhall)

Cheers guys after some help please

Hi look at the Connects2 units and ask the to supply a suitable adaptor.

Your aftermarket will need to be compatible with the Connects2 box, they can advise you on that if you go down that route.

The code is the VIN and getting the code is easy, programming it into a replacement stereo is tricky unless you have the correct gear to hook into the radio. The ebay sellers have the gear and can code the stereo with your VIN (see this listing).

I’ve seen some ebay sales saying that the device is decoded and plug and play so no beeping. I’m assuming the screen wouldn’t work still. Have to say that one you listed is a bit expensive for a radio lol! I thought

Is it likely they would give you the code as well incase whatever happens if you did purchase one of them.. I might want to get a second key one day. Assuming it’s a 1 code does all?

Is it the RD3 or RD4 stereo that would have been in mine?

Sorry couldn’t edit!

To add to my other comments above. I’ve just watched a vid on YouTube to code the stereo to the car using diagbox.

Surely it’s easier buying a 20 quid radio that beeps and then getting the diagbox and changing the vin in the radio configuration. Looks easy on this vid https://youtu.be/Ibuh210IgLM



Im assuming at 1 min the RPO is the car pass code? Or is that a code for Diagbox

Neither.

The RPO is the birthday code found in the door shut.

No, the radio code is just the VIN.

I might want to get a second key one day. Assuming it’s a 1 code does all?
No, that is not correct either.

Adding another C3 key is in several parts, if you want remote unlocking, turn in the lock or starting the engine through immobiliser too.
That would be a different topic in a different section. Keys and Radios are to very different things.


I don't know what you had fitted originally, sorry.

Ah ok, the security code on other cars is usually the radio and pass etc under 1. Didn’t realise they differ on here.

In terms of key just thought I’d I had radio code it would have been security.

I’m assuming I can fit any OEM radio as long as I code the vin?

If you have the tools to do that, then yes.
