What I would like to know, is it possible to upgrade the cdr-23 head unit with an aftermarket Alpine or Pioneer motorized touchscreen sat nav system. My research has all come back negative due to the fact of having the BOSE system with the fibre optics with the only suggestion to replace the wiring and amplifiers. Although not terribly impressed with the BOSE I see no real reason to rip it out and start again, and don't want to spend thousands doing it either! I also haven't found a OPC who wants to put the standard PCM in for me either due to the same reasons although the PCM appears to be a retrofit option on the porsche website. Probably don't want this option in any case now as I have read in the forum that the PCM is outdated in comparison to the new kit in the market.
can anyone help?
