I found it. The NAV unit in the trunk had the fan always running. Diagnosis was to pull into a dark garage and turn off all the lights to look for any light bleed (idea was that there was a light on pulling battery power, 400 mA at 12 volts ~ 6 watts which is the wattage of a incandescent bulb for some interior lights). I didn’t see any lights in the dark (other than the security indicator light), but did hear the fan going. I unplugged the NAV unit in the back and the power draw went down to ~20mA.

I disassembled the nav unit looking for damage or any reason why it may not be working and could not find anything. It won’t eject the DVD under any conditions, so it may be damaged or not repairable anyhow. For now, no Nav system.
