Dear Garmin,
on my both nüvi® 3597LMT trip computer (see Owner's Manual A Mar 2013 190-01580-00, page 6) counts distance too fast: I've done nearly 60000km in one year, but the trip computer show on boths trips A and B unrealistic mileage of nearly 300000KM !
Firmware on board: 5.10.
have You heard of that phenomenom ?
Greetings
