I recently installed an Alpine IDA-X001 into my '00 Ford Mustang GT with the Mach 460 audio system.

I ran a female to male USB cable from the back of the Alpine head unit to a USB drive. When I try to read the USB drive, the headunit gives "device check" or some other message which basically states there is no USB drive attached.

How can I fix this issue?

 

The drive is already formatted to FAT32. I tried a different USB drive which is also FAT32 and it works with the alpine. Problem somewhat solved...
