Hi.
If the solution that do not smell of burning electronics at 99% only need to connector correctly (not GND connect)
80% of tomtom's, which to us are getting damaged when the car is started. TomTom's are very sensitive. I say to each customer at the time the car is started tomtom was disconnected from the charger.
