Accepted Answer

The problem here is if the nav unit looses power while it is powering down it locks the unit up. You can try to perform a reset on the unit by unplugging it after the red light goes out. Then retry it. But most likely you will need a new nav unit.

would it be possible that it is an inline resistor.

Answer

There are no inline resistors to it. I would check to see if the red light is on in the nav unit.
