some USB sticks not working on 700bt — AVIC411 Forum Archive

Hi,

on my AVIC-F700BT Sandisk Cruzer micro (4Gb & 8 GB) are not recognized. USB stays gray.

My Sony (2Gb) and Imation (4Gb) are working fine.

All sticks have one partition and are in fat32 format.

Anyone with the same problems? Is there a list of working USB stick?

AVIC-F700BT with Firmware 2.001

I just got my F90BT installed and am having the same problem with my 8GB Sandisk Cruzer Micro. In my previous vehicle I had a Sony head unit that wouldn't recognize this particular device either.

Try Formatting with no partitions, FAT32, 32 kilobyte Allocation size. I'm using a Verbatim 16GB Flash Drive and had to wipe it clean but once that was done it works great. Save all the junk that is on it (back-up) first so if you want to reload you can.

I've got a 32GB but have not had a chance to do this yet. Once I try it I'll re-post.

I have an 8G Cruzer, it would not get recognized after formatting. Theres a trick, you have to boot your unit then plug the Cruzer in just a little until the light comes on on the Cruzer, then quickly push it in the rest of the way. Then it will be recognized. This makes it pretty much useless to me as I'm not going to do that evertime i turn on my radio.
