Forgive me if this ground has been covered. I have a Garmin in my Jeep and have been bidding on Ebay for motorcycle units, unsuccessfully so far. In fact the Buell unit is a Garmin. So a friend just won a motorcycle Tom Tom at the local motorcycle show. It's available to me brand new in the sealed box for a screaming hot price. Is it stupid to embark on two systems from a download and map upgrade perspective? I'm very new to this GPS business and would appreciate opinions from those in the know. Thanks.
