Did you try loading a single mp3 on the drive to test?

 

USB cord issue maybe??? My ALPINE did not like the wire it came with. I use a Tech Armor USB Cord now. If not the wire you may have to reboot the head unit...
Worth a shot....

 

USB thumb drives are inserted directly into the port, so no cords are needed.

 

As far as I know, it is only the white USB port inside your console that should be used as the media connection to your infotainment center. I think all the others are just for charging.

 

This may sound weird but what was the temp outside? I realized that with very cold temps it doesn't want to read my USB. Once it warms up a bit it's fine, and every other function of the radio works fine.

 

In my truck, all 4 ports recognize media. That being said, have you tried not putting so much music on the thumb drive as a test?

There is a limit to how many files the Infotainment system will index. However, I'm not sure what happens when you exceed that limit... does it quit recognizing all files or does it just fail to recognize the files that exceed the limit. That, I'm not sure about.

 

Definately try using a drive with just a few songs first. 30 Gig is a LOT of music , and the radio only supports so many folders. You might have to restructure your music.

 

Make sure you're formatting the flash drive as FAT32. If that doesn't work disconnect your car's battery for 10 minutes so it resets the radio. It could be something as dumb as the radio being hung up. That's happened to my '09 Outtie a few times. :/

 

After having the Android Auto update done last week, the USB in my console stopped reading my MP3 thumb drive today. The one underneath the head unit still reads the thumb drive fine.


Anyone else have this happen?

 

Mine seems to with most of the time but every now and then while using it, it stops and says media not found. I have the USB plugged into a cable in the console so I just unplug and rep lug, poof Wala, it is back at the same track it was playing.

 

I got my Colorado 7 weeks ago, and have had problems with the media center twice. Yesterday it wouldn't see the ipod or the flash drive. The DIC and media screen didn'the display the same.. I left the truck for few minutes and it reset itself, but took it to the dealer today anyway. Supposedly there has been some issues and the dealer did 2 software upgrades. Too soon to tell, but everything is back to normal now.

 

I have a new 2016 with the Bose system, and the only USB port that does anything is the one right under the radio, on the front console.

None of the 3 ports on the under arm area or for the back seat passengers work at all. No power, no connection, no charging. Dealer says a power board on the stereo is defective(truck is 1 month old and they never worked from day 1) and the part has been on order for almost 2 weeks now.

 

I guess we have a confirmed known issue. I have tried all the basic troubleshooting to no avail. Also realized that both ports on the back of the console are dead too. Scheduling service

 

The USB Device must be formatted to FAT32 file format prior to use
