First off...I was originally using a 4 gig kingston USB drive (formatted FAT32). If i connect the kingston drive to the USB cord after the unit has powered up..everything works fine. However, if I leave the USB attached and later restart the car...the unit has a hard time booting up (if at all). I also tried using a 8 gig Xporter XT...with this USB flash drive, the unit will boot up however the USB won't show up in the AV source (the USB icon is grayed out). Am i gonna have to connect/disconnect the USB drive everytime I start the car in order to use it?
