PCM HELP!

[waynerp]

Hi One & All

OK i have just collected my 2003 cayenne s & im a very happy chappy.

But the car has the standard CDR23 system and i want to upgrade to the PCM.

i have done some investigating and spoke to my local porsche dealer who tell me that the car was originally fitted with a PCM.

i've had a look in the boot (trunk) sorry im in england!!, and it has the 6 cd changer but i cant see any dvd/ cd player for the sat nav, so i guess at some stage somone took out the whole system for whatever reason.

if porsche have made an error and the car was originally fitted with the cdr23 do you guys know if it will still have the wiring to fit a pcm, or am i hoping?

what is the easiest way to check if the wiring is fitted, and am i right in saying the sat nav dvd/ cd drive is in the trunk somewhere?

many thanks in advance

Best thing to do is look at the PCM Installation TSB and see which parts are missing.

what is the easiest way to check if the wiring is fitted

look at your codes for factory options installed or send me your vin (by PM, pls dont post in the forum), or if your dealer is closer ask him to check against your vin what options your car has

A MY2003 Cayenne would have been fitted with PCM2.0, which uses the CD drive in the main unit as the navigation drive. From MY2005 they fitted PCM2.1 which has the separate DVD navigation drive under the seat.

I find it difficult to believe it was downgraded from PCM to CDR23, but as has been said, it would show on the options sticker in the maintenance booklet.

Hi -- like Loren noted check out the TSBs. (And be sure to become a contributing member -- it's worth it alone just to access the TBSs.)

Did you see the Glossary link too ;)

TSB = Technical Service Bulletin. Porsche published these for updates, installation, and problem fixes.
