I installed a 2011 Usb radio in my car. The usb works great for playing music on a flash drive. The 4 gig drive works, but a 16 gig isn't recognized.i checked my manual, but it doesn't say how large a flash drive you can use. I don't no if my flash drive is bad or if the radio can't read from a 16 gig drive. Does anyone have any info

 

Most likely the drive is the problem, can you delete and reload the info? Is it the same formatted info as the other flash drive?

Just a thought to test it!

 

I reformatted the drive using the fat32 put the music back on, and it still says not recognized. I tried putting music in a folder on the drive, still doesn't work.i just wondered if it was to large for my radio, or just a cheap flash drive. It's a verbatim brand. In my manual it says nothing about how large a flash drive it will read.

 

Does it work in any other devices?

 

16gb are dime a dozen.. Grab a new one, put songs on it, and see what happens. If it works, you know it's the drive, if it doesn't, you know it's the size. Either way, you get a spare 16gb that can keep a ton of music on for you. :)

 

It works in my PC and also my tv. That's ok if it only recognizes the 8 gig.i was just curious if anyone was using a 16 or bigger. Yes I will get another brand and try that. There cheap, and I can use it for pictures. And data if it also won't play in my car. Thanks

 

8gb was the largest size I got to work in mine. Used a Kingston

 

The radio was probably made before 16 G was a possibility, might also be USB 1.x v USB 2.x v USB 3.0 problem.

16G drives are relatively new, just last year they were NOT "a dime a dozen". They got really cheap once USB 3.0 popped up. Not to mention SDxx cards are the "new" thing.

 

The Super Talent Pico Mini up to 32gb work great. I have several low profile.

Once in a while the radio wont reconize it. I found if I remove it and plug in my iPhone via usb cord then swith back to the Pico drive it will works for a long time.

I grinded off the loop on the end to make it smaller.

 

I bought a 1 TB solid state drive since I have about 15,000 songs now and 800 or so videos and got tired of the thumb drive swapping thing. If the drive has a USB connection it might not compatible with the head unit USB as they are USB 1.0, 2.0, 3.0 and now even 3.1!!!!

I would check on line with the head unit company to see what they say as I do with Pioneer and the AVIC forums.
