I had one of these fitted to my golf before I got my new head unit. thats where I had it installed.
if your anywhere near central scotland mate, I could give you a wee hand fitting.
there is a red and orange wire that you may need to swap with each other. to see if u need to do this fire the car up, make a call and turn the car off and remove keys, if the parrot display doesnt say goodbye and just turns off u need to swap they cables.
also if u send a truckie a msg he might be kind enough to sort you out with the wiring adaptor you need as I sold him my parrot to him but he wasnt puttin it in a VW so he will have this going spare.
