I have the uconnect 5.0 stereo without nav or sat. Recently it started rebooting every 4 minutes. I have no usb functions as well.
Its very annoying! I called uconnect and they said that the stereo is up to date for a update. I took it to the dealer and paid $120
just to tell me that the radio is no good. The car is not even two years old. Any ideas?

 

Replace the radio. Things break. If it's not even 2 years old, warranty will cover it.
