Periodically all of the sound goes out, not just the radio, but the nav, turn signals, everything. Reboot, it's okay. Yesterday, the a/c, the SiriusXM radio, Slacker and iPhone integration went haywire. The USB still played and the sound worked for other things. Reboot, it's okay. I've done probably close to a dozen reboots by now in the 2 months of ownership. Is this a high number, low number pretty typical? I'm still on 17.5.28 so maybe that's the culprit.
