Hi, I have just seen this thread, and wondered if anyone would be able to give some advice

My mum brought this Parrot handsfree kit and got it installed straight to her Astra, by the shop she brought it from, changed the car and never got round to fitting it again, so said I can have it ..

I've tried getting my head round the wiring, but the ways I've tried, don't seem to be working, I have brought the adapters for the ka wiring, and have an aftermarket headunit, I noticed on the receipt, they charged extra for the wiring (I can upload a photo of this if easier).

Do I need to remove that wire and put the adapter ones I brought in? Or attatch that to the current wiring for the parrot. Sorry if this doesn't make much sense, I've tried explaining it best I can :d.

Thanks in advance for any help and answers
