    PCM - Differences between 996 and 997

    Hello,

    i'm a brandnew owner of a 997 TT (basaltmetallic black, black leather interior, Tiptronic, PCCB, PCM, ...).

    The car before was a 996 Turbo Cabriolet (silvermetallic, black leather interior, PCM with CD-Changer and external phone, ...) and overall i was very satisfied.

    But now, after approx. 1500 km with my new 997 TT, i ran into some open issues:

    Remembering my old 996 TT Cabriolet, when using my PCM (Navi, Sound, Telephone) everything was very fast. Using the disk changer changing tracks (skip forward i.e.) only takes a second to display the correct track information on the PCM.

    But now with the all-new 997 i realized that there is some sort of time lag for example when switching tracks on the single CD Player. It almost takes 2 to 4 seconds before the display gets updated.

    Furthermore when using the Navigation it seems to be very slow and unresponsive.

    Does anybody here in the forum made similar experiences?

    I also found the CD changer on the 997 to be slower than on the 996. Strange!?! Not Nav however.

    Hello Jeannot,

    so this is the first positive answer i got so far ...

    What about the Navigation? Faster, equal or slower as compared to the 996. Mine is definitively slower....

    The 996 I have has the PCM 1 8bits...so you cannot compare the navigation 996/997. But the CD changer is definitely better...

    Hello Jeannot,

    how do you check if it is Version 1, 8-bit and Version X, Y-bits????

    Here useful info.

    997 is PCM2 / 16. Not sure for software revision.

    I think the 16-bit version as the one with the widescreen.

    Re: PCM - Differences between 996 and 997

    There are 4 basic versions of PCM.
    As sorted by "latest technology".

    The ones fitted in pre- 2003 996s (small screen)
    the ones in 2003-2005 996s (larger screen)

    and the 997/Cayenne version (screen similar to 03-> 996s)
    which are very similar.

    It seems there are numerous bugs in the new technology.

    Re: PCM - Differences between 996 and 997

    Porsche betting get cracking on a VTG technology to handle the PCM lag.
