I installed a Z120BT in a customers 05 Escalade and it randomly reboots. Nothing seems to cause it, as it does it at any volume, no volume, and when the vehicle is sitting still. I removed the radio, checked everything, and while it was on I installed it back into the dash, so essentially if there was a loose connection it should have happened, but didn't. I'm using a PAC OS-2Bose harness.

 

Are there any firmware issues that may cause this?
