Could you explain how the tablet woud work with the Garmin?
At home I will create a route using something like "ride with gps" and then load the route on the Garmin. However the ridewithgps program is web based. So, if you do not have web access, is there program you can download to the tablet, plan a route, then upload to the Garmin?
Does Google maps create a route that is Garmin compatable, and can you use Google maps without web access?
Sorry more questions than answers.
