This has been a great GPS so far. One major negative for me is that the XM antenna is where the XM activation is stored and once installed on the motorcycle XM is not available in other vehicle if you do not have the original antenna. XM portability was why I brought the Zumo 665. Was not clear how it worked and now that I know I would not buy the same unit again as a result.
