Nuvi 650 Touchscreen Problems

 

My Nuvi 650 touchscreen has become non responsive on three occasions now. Researching the topic on the net I found references to problems with the 650s with certain serial numbers. Mine fell into that category. But, the pattern I have noticed is that when it fails it has usually been in a hot environment for a while in particular a hot car. This third time revealed a pattern that I want to share. After bringing the unit into a cool air conditioned environment for a couple of days the touchscreen starts working again.

I retract what I said in the original post. I just unplugged the USB from my computer and now the touchscreen is non responsive again. I guess temperature has nothing to do with it.
