USB devices not recognized in MyLink

2017 LTZ with 8" MyLink.

 

Periodically the truck fails to recognize USB devices when I start the truck, including USB flash drives and my phone via Android Auto. If I press the Media button, I see the phone via Bluetooth but I do not see the flash drive. It doesn't matter which USB port I use and the music was playing via the flash drive before I shut off the truck.

 

The Projection button on the radio screen does not change to Android Auto as it would do under normal operation.

 

This will likely be a warranty issue but if anyone's seen it beforehand so I can point the dealer in the right direction that would be helpful.

I have been seeing the same issue with my 2017 Tahoe.  the dealership has replaced the head unit and a few others things and we still have the issue of the vehicle not connecting to my phone.  I have had numerous chevy loaner vehicles and in each one of them I have had no issue.  Last December the regional manager told me to give him until the beginning of this year to fix the issue and if they were unable to and I was not happy he would approve a buy back with no depreciation on the vehicle.  That manger bamboozled me cause he left and now the hew guy is dragging his feet.  I am looking at hiring an attorney because Georgia has a lemon law and my vehicle has been in at least 7 times and I have been without my vehicle for at least 2 months because of this issue.

      Tire psi

      By Chuck FB · Posted

      Glad that worked, and in this case that is all on Autel for somehow dropping the ball for not updating the GMC section properly.    I believe in the basic section or unless it is in the advanced, when one does a check of lets say individual sensors for what the pressure is ( and it shows a temperature as well ) , I think it picks up on what the model number of the sensor is in a certain section where you choose "OE" sensor or at least mine is telling me what the model number is and matches to what they actually are and that is the number I quoted in a prior post.    I don't recall now if I had said prior that I discovered with my truck anyway that no matter how low I set the placard pressure for the rear tires, if the physical pressure is under 35 psi and I drive it for about 15 miles the pressure warning will come on for one or both rear tires. I am speculating that there is something else in the trucks system that over rides the placard pressure setting once it drops below that minimum pressure to run a metric LT tire at. The weird thing is it does not trigger right away after driving a shorter distance, it took that longer drive for it to trigger. Just something to keep in mind if you were experimenting with pressures below 35 pounds for a tire designed for lower pressures ( larger than stock floatation series tires ) and not being overloaded of course.

      I've seen a scant few YT vids on them, but it's always in a performance application.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      No clue. Service advisor said he'd call me this morning, which I'm 99% sure won't happen. They had the truck 5 days, and I didn't hear a peep. Finally had to call them yesterday. I guess they'd be content to just let the truck sit in perpetuity.

      Tire psi

      By jgaudet99 · Posted

      I had a little bit of time before I left for work this morning, so I plugged the scanner back in, and I selected Chevrolet Silverado instead of GMC Sierra, and the very first option was for a 2026 so I selected that one and I seen at the bottom it had the option for psi change unlike in the 2026 GMC Sierra, I selected that option and it took a little longer than the usual vehicle not supported, and sure enough I got into it, and it let my change the psi values.. I no longer have the low psi warning light!   Thank you for recommending me to try it under Chevrolet instead! I can confirm this device does work for a 2026 GMC Sierra 2500 hd 6.6 diesel  just have to select Chevrolet Silverado instead of GMC Sierra.   Maybe I'll contact Autel and let them know of that issue and maybe they will fix it for the GMC option  because some people probably return the scanner due to it not working under GMC Sierra.
