I am considering getting a new GPS for my bikes. Would like to know if the consensus would be to use the ZUMO or one of the MONTANA units from Garmin. I know the ZUMO will give turn by turn navigation and link to the phone, but does it have any topographic capability? Does the Montana have the turn by turn nav available and will it link to the phone? Anybody have both? I have an FZ6 street bike and an 08' KTM 530 EXCR Enduro and it would be nice to share the unti between them.
