G'day, Can anybody help or give me some advice on how to get my new GPS to work. Every time I try to load a route that's been created in Basecamp or on the unit itself, the unit (Montana 680T) either turns straight off or the screens freezes requiring the battery to be removed. The unit was purchased at Jonny Appleseed in Annerly Brisbane mid this week. I had problems with that unit and contacted them to arrange a replacement. They quickly conceded that the described issues were a faulty machine and offered a replacement. Replacement received today! Same F-ing issues. Is it me dong something wrong or is it the machine? Any help or advise appreciated before I throw this thing out the window.... Cheers.
