There is a new development this morning.
When I got in the car this morning, the lcd screen was blank and the backlight was on. I left the back light off last night.
Now the screen stays blank, with the backlight on. There is no response to any of the buttons.
I disconnected the unit for about one minute and then re connected. Same thing; screen blank, and backlight on.
Except for not resetting current data after 7 minutes, it seems to work fine for a day and a half.
Any ideas?
