Really hope some tech wiz can help here, topic title kind of says it all but in detail..
Vehicle is a 997 C2S 2006 with PCM 2.1 and v3 software with satnav and bose, no CDC.
I installed the GW 500 and initially all was ok, worked perfectly. I then did the firmawre upgrade with FW from the dension site. the .ROM file was deleted from the USB stick, but no .bin file to say new firmware upgraded. Now when i start the unit the PCM does not see a CD Changer and the ligt on the dension flashes a few times and goes out...not good.
Is there any way to recover from a failed firmware up
