In early June 2012, I bought the Navi for my motor home (5 t). Commissioning proved to be easy and went quickly. Charge the current map took a little longer, but it made after the start of the computer on its own. The Navi has already saved me on the 1st trip to Croatia 2 times in front of a total closure of the highway after an accident (in Italy) and discharged in time. The instructions given by the navigation system are short and clear, not a permanent annoying repetition like in other Navis. In short, I am very satisfied and can only recommend it to all campers. Also, the price is acceptable. A downer there, however. I am avid cyclist and use the Navi also here for new routes. Switching to cyclists mode is simple. A test on known routes revealed but nevertheless some weaknesses. It wanted me to make a few detours, though marked bike routes have a shorter route just expelled. This could for the manufacturer still some need for improvement exist. But since I have bought the Navi primarily for the mobile home and am also very satisfied there will be no devaluation.
