Only 400 miles on my Rebel and have only one complaint.* Uconnect satellite receiver frequently locks up where i cant change the XM channel.* The screen wont respond and seems to queue up commands. Then 4-10 minutes later they are all executed quickly.* I can however switch to FM or apps so the UI isn't locked.* It's just the sat tuner locks up.* I see a lot of posts on web about similar issues. Doesn't look like there is a software update yet. Turning off tuck and restarting makes it go away, but not really an option while travelling down the highway. Anyone else have this and found a workaround?
