Does anybody know if you go to VX with your car chassis/reg no if they can tell you what the radio code is for your vehicle? that's assuming it still has the factory fit stereo!

[Marks DTM Calib]

You can get the vehicle security card, it has the Key number, vehicle security code (required to programme a new key) and the radio code....its about 15 quid ish....

[Salty]

Thanks, I will try getting one.

Yep, iirc, its called carpass. As mark says, £15 ish from dealer, BUT you have to prove ownership, so ring dealer to find out what they need first, eg logbook etc...

[Salty]

Thanks for the tip, hopefully my V5 will have arrived by the time I get home

[RonaldMcBurger]

Or try popping the radio out. You would not believe the number I have seen over the years with the code written on the unit itself!

[sounds2k]

bought one a couple of weeks ago for mine ...  £16 + VAT (£18.80). Took the V5 with me which was good enough. Dealer gave me a hand-written note with the codes a day or so afterwards, the proper car pass arrived in the post about a week later. Turns out that I didn't need the code when removing the head unit after all (Siemens NCDC2013) ...  

[Salty]

I've got the philips sc804 with autochanger in the boot, so probably will need the code.

[TheBoy]

The older ones have seperate code for radio and for the cd changer in boot.

[Salty]

mines an early 97 so probably will need both

Yes, but both will be on carpass

[Salty]

Thats good news. I will have to get it as I need to remove the central console to replace some duff bulbs.

I found that out when i fitted my CID, apparently the headunit/display are married and are coded for your ecu through tech2. You can remove them from your own car for as long as you want, they'll still work when you connect them all together again.

If however you fit the headunit or screen to another car, which obvoiuosly would have a different ecu and immob. code than your own it would then lock up.

So my local Vauxhall service chappy says.

Not quite, the display and unit are coded together and not to the ECU at all so the two have to stay together.

Which means you can swap the pair over to another car but cant fit a second hand display or unit to an existing install unless it has been de-associated with tech 2 first.

That sounds a bit more sensible.
