Thanks a million, my wife, 2 young boys and I are on the tail end of our vacation, driving from Chilliwack, BC, Canada, to Los Angeles and back, stereo died 10 miles outside of Seaside, Oregon tonight. Almost lost my *bleep* when it went down. Checked the forum as soon as I got situated in the hotel and your comment was 100% spot on. Resolved the isse, now I can breath easier knowing we have a stereo and GPS for the last leg of our drive home tomorrow.I looked around a bit and only saw random posts about his topic. If you have a newer Cruze with the touchscreen MyLink and your screen is blank.... here's how you fix it.
First off, what you'll notice is that the USB port isn't functioning and no matter how many buttons you press the MyLink won't turn on. After speaking with the Chevy Infotainment team I've learned the reason this happens is that the radio is clearing it's cache (desk) of stored memory (in basic terms it's like a cookie but for your stereo).
In order to return MyLink to a functional unit you have to shut off the car, open the door, close the door, don't lock the car (I didn't anyways) and let it sit for 5 minutes or longer. Once you turn the car back on the system will be reset and return to normal. Don't worry, none of your settings will be deleted.
Hope this helped you out!
