My F90BT tends to intermittently switch off random play from SD/USB. It also "forgets" what track it was playing on SD/USB, starting over at the first track it finds on either storage device, and the clock reverts to 12:00 until it's auto-corrected by GPS within a few minutes of startup. All of these things happen after the vehicle has been shut off for roughly 2 hours or more, However, the AM/FM/XM presets, EQ, fader, etc. are not affected when this happens. I'm on my second F90BT, as the first one had an MSN Direct problem for which I had it exchanged. Both units had 2.0 firmware, and ex

I've had the same issue without swapping cards or drives.

My F90BT came with the 2.0 firmware preinstalled & I have the same issue as you with both SD and USB. However, it seems to be related to how long the unit is turned off. After roughly two hours or more of not being used, my unit shows the problem. When the problem appears, the F90BT will play the first file ("file 1") it finds on the storage device. The SD card I've tested with is an 8GB SDHC with 900+ tracks on it in numerous folders, while the USB drive is a 2GB with only 12 wav files on it.
