Hey all, Looking for some feedback on a 30 pin extension cable like the one pictured below: I've got a Pioneer headunit in the car which uses a special cable (see below) with a 30pin on one side and a special connector on the other and it's about a foot or so too short. Due to the special connector, I can't just add a simple usb extension cable. If any of you out there own the extension cable, I would like to verify that it does transfer video/music AND charges your device at the same time. Thanks!!!
