Hello I bought a TomTom XL in Brazil (I live in Brazil) - Navcore is 8.083 and current map is Brazil V855.3026 I am traveling to France tomorrow and would like to find a map of France What version should I look for to run with my Navcore version? Is it possible to update the Navcore version to a more recent one, and use map v8.85 4009? How should I install the new map, and do I need a unlock whichever map I will find? Thanks
