First things first I'm a noob forgive me. I just installed my Alpine IDA-X305 also Alpine KTP-445 power pack. sounds great install was a pain. I don't have the USB/IPod connecter it came with but I have the extender that goes from the back of the HU. I tried using my Apple USB Cord And Error code Came up NO USB DEVICE. Using Iphone 4 Version 5.0.1. Do I have to use alpine connecter. does not make any since. any ideas, suggestions would be awesome thanks in advanced.
