We have recently taken on our first MH which is a Fiat Swift Lifestyle 686, fitted with built in TomTom - featuring a standard 'car' system??!! Does anyone know if it's possible to upgrade it to the Caravan/Camper version? (Which we have on our standalone TomTom, as ex-caravanners). Seems mad that it's fitted with the car version. If it's possible, do we just use the USB connection? Thanks in advance.
