An alternative is to not use RWGPS but instead use Garmin Connect. The maps are OpenStreetMaps OR Google, so essentially the same as RWGPS. I find building "courses" (Routes in RWGPS speak) to be as easy in Connect as RWGPS.

Then use the Connect app on the tablet or a smartphone to BT sync the Connect route to the 810.
