ive had the same problem.only two head units on the market today run the latest ipods (fusion ipod one and the latest alpine ipod only head unit). this is because apples reverted back to using usb power i think, instead of firewire? (or vice versa, cant memba) rapid radio sell an adapter which will make it charge again, there bout 150. its called the scosche passPORT, its a charging adapter for the latest ipods and iphones, you can plug it inline with any ipod dock or plug into the base of your ipod and it will allow you to charge it. i use it on my "ipod ready" head unit and it works mint
