Hi,

I have had my TomTom Superior hardwired into the fusebox on my 2023 Scala.

The TomTom shows that it is charging when the engine is running, but after a few days it dies from a flat battery, as if it is using more power than it is getting.

Did anyone have any suggestions of what the problem could be. Thanks.

The only thing I can think of is that the Tom Tom is not shutting down when the ignition is turned off. Maybe it's been hardwired into the wrong circuit?

In the old days we had permanent live and ignition controlled circuits.

In modern cars we still have permanent live and ignition controlled but also circuits controlled on the canbus or by the car's CPU.

Thanks for the reply Aldfort. The TomTom does say it is shutting down when I switch off the engine, so i think it must be something else. Thanks again anyway.

Does the tom-tom battery discharge if it's disconnected from the car?
