Hi All
I have a 2007 porsche cayman and all of a sudden have a problem with the PCM. I can have a CD or Radio playing then all of a sudden the music will stop and a message comes up NAVIGATION SYSTEM NOT AVAILABLE then followed by another message NAVIGATION SYSTEM IS BEING STARTED then it will go back to normal and the music will come back on. I thought it may of been the navigation system CD so i bought another cd and the same happens its driving me mad as it is now happening every 10mins or so. The navigation system works ok when I use it

please does anyone have any idea

thanks

OPC changed the PCM unit several times, then i upgraded the phone (from an Sony Xperia to a Samsung) and the problem went away immediately
