I installed a D3 with the 920 XM Receiver about three weeks ago. Three or four times now I have had the audio from the xp fade in and out for 30 sconds or so, then I lose audio completely. I still get all of the data on the screen, just no audio. all other audio sources continue to work fine. Shutting the car off and restarting (removing Acc power) fixes it.
I have checked the connections on the XM receiver and on the D3. Anything else I can check?
Thanks
