Sync issues (My touch)

So last night my SYNC system started acting up. The USB I keep a music thumb drive in froze. Then the system did a maintenance reboot numerous times. The radio was cutting on and off. When I cut the car off and opened the door the sync and stereo remained on. Today got Navigation SD card fault. I have an appointment with the dealership Tuesday. Can all of these symptoms come from a SD card fault?
