How much is my old PCM Nav worth? I think I should sell it?

99664210502EFR PCM Control Unit (replaced by 996.642.905.04.EFR)

99664212200EFR Computer (replaced by 996.642.122.03.EFR)

These are PCM 1 parts and the two parts must work together (by serial number) and will only work in a MY01 or older 986 Boxster or 996 Carrera.

The last number is an older amplifier (M680 with digital processing).

Unless someone has a broken PCM 1 or want s spares the NAV parts are very outdated.

Also, the PCM 1 is pretty hard to retrofit since the wiring is not here on cars that did not have it.

You can post it for sale in the For Sale - Parts forum if you like and see if there is interest.

The amp and 6 disk CD changer are more popular options.

But I doubt either will much more than $100 each... again you are welcome to post them in the For Sale - Parts forum.
