PCM Failure

[dbth]

I've had intermittent problems with PCM on my 06 Boxster S over the last 18 months , system cuts out and occasionally reboots itself.

Porsche diagnosis is PCM unit needs to be replaced, very costly since I'm out of warranty.

Today I received this message:

SYSTEM FAILURE -

PHONE, AMPLIFIER, NAVIGATION SYSTEM AND CD CHANGER ALL UNAVAILABLE.

So it appears my audio , nav and phone are dead. The car itself runs great , I am the original owner.

Anyone here have any similar issue or suggestions.

Thanks ...
