BenBoo: I have heard that before. I think between Samsung, Strava, Map My Ride and Bontrager, this is a technical clusterf**k of classical proportions. Luckily, we're not in a foxhole somewhere waiting for all the systems to work together to get us ammunition.
My solution is going to be the one you mentioned. I'm going to get dedicated bike computers that actually speak to the DuoTrap. I didn't want more screens, but then, I don't want hills and headwinds either.
