PCM Radio only Receives with Engine Off

[jcuticchia]

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 diagnostics and said that it showed nothing wrong.  The dealer said that I would have to get a replacement PCM and then quoted a price in 4K range.  Has anybody seen this type of problem before, and if so is there a solution?  Also if I have to replace the PCM are there less costly options than 4K.  Thanks for any suggestions in advance.

4K for radio reception seems like awfully expensive music.

 

Have you asked yourself and the dealer how it's conceivable that a flat battery can screw up the PCM?

[jcuticchia]

Yep.  They said when the battery was jumped a power surge hit the PCM and blew out a circuit board.

Ah, OK. The jump start explains it. There really should be a clear warning about the potential hazards of jumping modern cars.

Check out Del Rey Customs in CA or online. They have a kit to install a better entertainment system in the 987.1. 

Its a Pioneer 4200 and has the wiring to integrate with the factory Bose amp so all works, just better. Even comes with trim that matches silver dash trim.

i have the options for rear camera and satellite radio, both add value. 

Now also has Apple Play if iu are an iOS person. 

Full meal deal about $1800.
