At first I was well impressed with this SatNav. Easy to use and set up. After the second day of using it the speech was garbled and the unit kept switching off. I sent the unit back and within 3 day's I had a replacement sent out. The replacement lasted about an hour then it lost the GPS signal! I emailed Garmin for help and they sent me instructions on how to fix it, it wasn't just a case of switching 'Demo mode' off by the way. Guess what? this unit kept switching off even though auto time out was set to never. I managed to have the patience of going through several re-sets untill it started working again. I have been using the SatNav for just over a week and so far all is ok. Would I buy another one? Nope.
