Hey all. New to the forums here. Just bought an Alpine iDA-X305 and downloaded some .apn wallpapers to customize my deck, the files are on a USB thumb drive, when I plug it into the deck I get the list of .apn files but when I hit the "enter" button to download them to the deck, nothing at all happens. I've tried several times now and I'm wondering if I'm doing something wrong, missing something, or if I got a defective unit. Thanks for your help...
