Hi. I have been given a GO 550 Live and the current map update is from 2009 [835.2419]. I believe that this device cannot now be updated with current maps but I'm working on the basis that I can update the maps to a version which is newer than my existing version. Has anyone else managed to optimise their device in this way and, if so, where were you able to download it from? Any help hugely appreciated. Thanks. Steve.
