In Albuquerque, I took my Land Crusier to RNS Auto an independent mechanic highly recommended by Toyota Land Cruiser folks. The owner/manager checked it all out in the parking lot--fuses were fine, heater, fan, and air conditioning could all be run off his computer while the computer was plugged in. He suggested the nav. head unit was bad, but then I mentioned that every other system on the head unit was operating perfectly.
He disconnected the positive lead off the battery, put a jumper between the positive connector and the negative side and let this stand for about five minutes. This drained the capacitors completely zeroing out all power in the truck. He connected the positive lead back on the battery, started the truck and all systems were go. Everything was back to normal. He mentioned that many folks would replace the head unit almost automatically and continued saying that these computers were not much different than a smart phone meaning that it was good to reboot them periodically and if something like this occurs do this first. I had disconnected the battery earlier, but had not run a short from the positive to negative wires while disconnected--disconnecting the battery was not a full reboot. He said that if we were out and anything like this happened again, do the same thing to reboot all systems. He also mentioned that if this became an acute recurring issue than it would need to be addressed at some point in the future. He was not overly concerned about this occurance.
He asked for $20 beer money for his mechanics when I asked what I owed him for his time.
We are our way. I wanted to bring this to the group as a heads-up.
