I be pleasently surprise after use this unit . I read some horror story from some reviewer after I have already orderd it and even think about cancel . all you have to do be read the manual -lrb- which be short and concise -rrb- before you start and you should have absoloutly no problem . I read some review which complain of shoddy construction . not true ! the map that ship with the unit be work great although they be ship the newest map to I for free . for anyone that do any travel in Europe , this gp come pre-loaded with all of the european map as well as Canada and the US .
