I recently had a dead battery in my 2007 Boxster with PCM (no bose). Once the car charged everything seemed fine. The Navigator and CD work perfectly. However, the radio will only pick up stations when it is in accessory mode. Here is how it goes: Car running - no reception; turn off motor; 1-4-8 reboot; radio works fine. Turn on motor - 4 seconds later the radio no longer picks up stations (static). However SOMETIMES one station will come it. I did the MAIN-TRIP diagnostics and it showed ! PCM; ! SOFTWARE; Ck Navigator.
I took it into the shop today and they ran some dia
