CdC30 + GID help

[Scouse]

Hello my CDC30 CD player wasn't working on my 07 Astra TT Design, so I bought a replacement unit that came with a GID out of a car with Climate Control (which my car doesn't have)
Everything works fine, but as I now have a GID I want to fit a UHP4 ,
I assume that I would need both the GID and the CDC30 coding to my car. I have read that leaving it in it's current state can cause ECU problems? I'm near Pontefract, West Yorkshire, but don'ti mind travelling, the replacement parts are from a 5 door 09 Astra with the same 1.8 engine
Is there anyone near me who can marry these to my car?
I have the car pass the old units if that helps
Thanks
Gary

If you have the car pass for the new stereo and display, then you can program the uhp4 to it no issues.

You will need a reset/cleared bluetooth module, custom loom and mic.
Its simple to program in.

Hi Gav
Thanks for the reply, just reread my post and the last bit of the post doesn't really make sense
What I meant to say was I have the car pass for my car, but not the new/replacement units.
I have gleaned so much information from this forum that I owanted to give someone on here my money as opposed to walking into a shop and parting with my cash, a way of kinda saying thank you (if that makes sense )
