Has anyone had a problem downloading and itouch ipod onto the hard drive of the stereo in the new challenger. I connected my itouch to the usb port on the front of the stereo and pushed the buttons to copy the files and it says there are no files to copy. I have over 1000 songs on my itouch. So I hooked it up to another itouch, one that was just used in the same manner, and it says the same thing. Any help would be great.
