900BT My Unit's randomly cuts out, the rest of the functions are just fine I just don't have any sound. I don't get the noise for the touch screen. To get sound back I have to reboot the Unit. The sound will work fine for a couple of trips then it will cut out again. I checked a the grounds and power supplies. I have the Mute Bypass done and thats it for Mods.

What vehicle? I'd double check the amp trigger wire, blue/white.

Its on a 2007 Silverado No Bose

I used the schorche onstar adapter. I saw in another topic about the volume control setting itself to 0 but I have seen that yet. The only way I have found to get the sound back is to reboot.

Happens with mine too, usually when the system is finishing loading and I ask it to do too many things at one time (like change to the map screen).

It's a bug with the hardware/software, and the only fix I've found is to reboot.
