I have a weird problem with my head unit rebooting on me. Here is the problem I have had for the pat 4-5 months: I had a Pioneer F90BT installed in my car and every so often I get 2 pops from the rear speakers and then my head unit reboots. Other times the head unit reboots without the 2 pops. Last week I installed a new Kenwood DNX7190HD and I am still having the same issue. All connections were soldered and double checked so I dont think its a wiring issue at the head unit side. It appears to happen more often at the beginning of my drive. On a side note its been cold in Toronto for the past 4-5 months also and I am not sure if that is part of the problem. Anyone have any ideas on what could be causing my head unit to reboot? Its starting to drive my crazy.
