Dont know if anyone can help here...fitted a gateway 100 to my Concert head unit this morning...I can use the gateway mode which lets you select artist/album etc on the head unit but for the life of me cant figure out how to get it into Ipod UI mode, where you can use the iPods click wheel. This is on an 8L A3 and using a 1st gen Nano. From what I can make out from the crappy manual its something to do with selecting disk 6 and then track 2, but ******** if I can get it to do that, select disk 6 ok and then....who knows?
