Hi gang,
I'm interested in retrofitting a PCM into my 2003 Turbo. I'd like to have Nav and iPod in a factory form factor (call me crazy), and am wondering how/if anyone has done it.

Would the units from a Cayenne work, or just the 996 variants? I've tried searching, but it's either really straightforward, or no one has seemed to do it.

Thanks,
