When I plug the NAV-U220 unit with a SD card/formatted to FAT32 it never loads a USB icon to WINDOWS7 nor can AVIC FEEDS find the device. I know the SD is ok since I can read it on another sd card reader. The U220 module it's loading to windows. Ideas. Thanks

Just noticed that Pioneer only supports 32bit version of WIN 7 !!! That's poor, given a high percentage of PC's are 64 bit. Both my desktop and laptop are 64 bit. I'm screwed................ If they haven't gotten to supporting 64 bit by now, when ?

I got mine to work buy using the reset button while plugged in to the ubs port....
