The motorcycle SatNav "Garmin Navigator VI" is supposed to be a premium product at a price tag of £600. It comes with constant issues of poor battery performance and not being able to connect it to PCs. I have raised this with the Garmin helpdesk who told me that I need to purchase map updates before the device can connect to the PC again. When I pointed out that this device was sold to me with free life-long map updates I was disconnected without getting the problem resolved. I have constant issues with this very expensive device and the internet is riddled with similar stories. Save yourself the aggravation. Stay clear of Garmin. Buy a TomTom or use your phone instead.
