2004 Cayenne Turbo with Bose sytem, PCM is bad, can i get any PCM 2.1

Recommended Posts

Hi, im a new Cayenne owner, recently just bought a 04 turbo but the PCM doesnt work at all, no sound, doesnt eject the disc or anything, it will turn on but screen will show all black and once i push the power button it will just turn off ( you can tell the LCD is off not on with all black color). i did try 1 4 8 reset and took out the unit and opened and re flow with a heat gun, nothing helped, i believe i need another new unit.

My question here, my car came with factory BOSE sound, which means it has MOST fiber Optic connection for the factory amp, can i just get any 04-07 PCM 2.1 and plug in it will support the Bose amp (i looked on ebay, all the back connections are same compare to mine) or i have to look for a PCM unit off a factory Bose system car? thanks for reading.

PCM2.1 (DVD, N. America, and updated 2yrs ago) went from 2005-2008, yours is a PCM2.0 (CD slower and regional only, and not updated in 7yrs). It would take some re-wiring and a DVD drive to install under the passenger seat to replace the CD drive. It would be better for you to do a search on here and/or Rennlist.com and look into an aftermarket option. Some will still use the MOST system so you don't have to replace the Bose speakers, amd, and such.
