after trying the Garmin (back to Amazon), I bought the Tom Tom can, he afford to do its own course (from a seller of auto center Garmin can not, what I could see ...) so it looked pretty performant.Hélas in the first test, bug, bug and re-bug: the screen becomes black or returns to the menu, the trip will disappear and not put it back facade and a 250 km journey !!! shame because I thought I had found the "pearl" especially as this model comes out (like Garmin) .Incompréhensible from these two "major manufacturers" of GPs put on the market of such devices, not at all the point .de who are we kidding?. Fortunately that Amazon allows us to return a non-conforming article, thank you again for this recovery policy.
