I did a search here on CL and on Google, but was not able to find an answer. I transferred my USB Flash Drive from my previous vehicle to the IS. For some unknown reason, when I start the car, the system does not recognize the flash drive, unless I perform a remove/insert, where the system would detect it again. My music is organized into folders and does not exceed the 255 files limit. Yes, I know I can transfer the MP3s to my phone and do Bluetooth stream, but would like to know if anyone else have had problem and was it resolvable? Thanks in advance..

 

bump. I am also having the same issue with my usb flash. It doesnt recognize it, but I bought another and that one had no issues.

 

Same here, I went from a 16GB to an 8GB and it worked fine. Don't recall, I may have tried the 16GB, reformatted with FAT32 and still no go.

 

Did you guys format is with NTFS?

 

I think it has to do with the file system that the flash drive was created in.

 

Ya I think so. Formatting doesn't do anything I think another member did that with no results.

 

I wasn't aware that our cars can read USB flash drives. Is this for Non-Nav cars only? And where do you insert the USB?

 

new model has USB play back

 

From my understanding only 2012 and up... I have a friend with is250c '11 and doesn't have it. Mine is located next to aux port in center console.

 

Not entirely true, I have a 2011 AWD.

 

Anyone know if we can retrofit and 2011 USB reading into older ISx50s?

 

ah thanks for clarifying. I guess my friends 250c didn't come with that option if thats the case, because he was excited to know that I have it on my 2012.

At this point about retrofitting one, I wouldnt be surprised if someone just had the time to do it. But retrofitting it wouldn't be the issue its the hardware being able to read it as a usb drive.

Well I got tired of figuring this out with my flash drive (which died now), ended up using my old ipod which was way better it read the music files much faster and I have full control of all the music onto my screen.
