Head unit constantly rebooting. Completely unable to use the head unit. No longer functional. Unable to power the screen off. Very distracting while driving especially at night. Power button no longer works. Started about a year ago, then randomly seemed to of temporarily resolved itself until a couple of months ago. Head unit is now 100% nonfunctional and constantly reboots. No warnings when first occurred. Issue has been confirmed by independent service center. Puts myself and others at risk due to the screen rebooting on repeat and no way to turn the screen off. Extremely distracting and unsafe
