I have installed many different cd players into different vehicles. We recently purchased a 07 cayman, and I wanted to put an aftermarket navigation in the system (looking at the pioneer units).
How difficult is it to do this. I've looked over the articles on installing the factory navigation and it seems simple enough. The main variations from that install seems to be having to run the GPS antenna yourself rather than patching into the MOST bus (think that was the name of it).
Would you highly recommend doing the install yourself (if you are faily use to installing cd players), advise against it, etc?
Also - do you have recommendations on where to install the aftermarket gps antennas?
