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 happening and found a workaround?
