After we upgraded Android on my wife's phone, we couldn't get it to call out via Uconnect. We tried everything. Finally, after resetting the phone back to "factory settings", we got it working again. Uconnect is a nice thought (when it works), but it can't compare to Sync. I've had Sync for 2 years on 2 different vehicles, and 0 problems. I can't say that for the few months I've had Uconnect. UConnect seems way picky when it comes to types of phones, operating systems/versions, etc.
