I get in my car and start to drive and then adjust the volume and the unit just shuts off and the lights jsut keep blinking, the only way to make it stop is to eject eh navi dvd, and then it seems to work ok for a while but then will shut off randomly later while driving any ideas?

Check your wiring connections. The ribbon cable could also be at fault.
