Not sure if it does, but that U probably comes equipped with Ant+.

I'm quite interested in this too. Do you need a lot of internet data to record rides on Strava? Much cheaper than buying a Garmin I reckon.

Very little data, and if you are ending the ride at home, you've probably picked up the home wifi at this point !
