Can't be certain for the US, but in the UK the last updates for PCM1 both maps and software were in 2001. No longer supported by Porsche.
When PCM3 comes out, i guess the same will be true for PCM2, which really brings into question the trade in value of such systems.
This, and the fact that PCM can't be transfered between cars, was the main reason i chose a PDA based system.
