I've been battling with the PCM 3 shortfalls for a year and a half so here is my question, if you could replace you PCM with any current head unit, which one would you pick and why?

I'll do
the install as a holiday project with step by step pics.

 

You have PCM v3, what dont you like about it? I know it doesnt have rear camera but I think it's sufficient for daily use.

 

I'm just extremely frustrated that Porsche locks down the PCM 3 to VIN numbers so there is no way to upgrade integrated to a different PCM 3 with integrated XM satellite. I'm also frustrated that all three "external" ports: aux, USB and iPod all use the same channel so there is no way to have three device or even two devices plugged in at the same time without getting feedback from the othe channels. Very poor design.
