Random blank mylink.

Victory14red · March 13, 2016

Hey yall. I know there were other threads on a similar issue. But none totally fit mine. Being as I am taking it to the dealer tomorrow maybe someone here will have some extra insight and possibly a tab number.

Mylink screen randomly blanks out. Still has audio. Always comes back within a minute. Doesn't happen often. Maybe once a month/ biweekly? Mostly seems related to extreme cold or sitting in the sun for an extended period. Almost never reverts to the previous screen when ending calls via Bluetooth. Occasionally it goes back to where I was, however if I have radio and am using on star turn by turn then it just leaves it on my little DIC screen, which pisses me off. Also, the last time it went blank both the DIC and Mylink blanked out.

Oh, and one time my temperature display (ambient outdoor) got stuck at 64 for 2 days.

Any ideas? I know there was a tsb back in the beginning of 2014 for a similar issue. Anyone know if this fits the bill? I can't find the exact tab number but iirc the fix was a software update.

The "MyLink screen going blank while backing up" TSB fixed a lot of issues. I don't have the number. My work order for this just said "updated radio software". This was done on mine in March of 2014.

Well it's at the dealer now. Had to drop it off. Hopefully I don't get the good Ole "could not duplicate" answer.

I am a bit pissed that they overbooked loaners so they didn't have one for me

But that's not chevys problem it's the dealer

I just found this one, and it may be more related than the original bulletin.

Aftermarket Equipment Connected to Multi-Media Ports

October 23, 2015

Various infotainment conditions caused by aftermarket equipment connected to the multi-media, USB or auxiliary input ports may be found on some 2013-2015 ATS, CTS, SRX, and XTS models equipped with the CUE system; 2014-2015 Regal and LaCrosse models equipped with the IntelliLink system; 2014-2015 Canyon, Sierra, and Yukon models equipped with the IntelliLink system; and 2014-2015 Colorado, Corvette, Impala, Silverado, Suburban, and Tahoe models equipped with the MyLink system.

The infotainment conditions may include blank displays, flashing displays, error or update failed messages, the navigation map not loading, or Bluetooth or USB concerns. If any of these conditions are present, check for any devices plugged into the USB ports, SD card slots, or 12 volt accessory ports. (Fig. 9) SD cards mount almost flush to the port and can be difficult to see. Remove the devices prior to diagnosing any infotainment concern.

Many vehicles also have a USB port that can only be accessed by raising or lowering the radio display/control assembly. Verify there are not any devices in the storage bins behind the display/control assemblies, if applicable
