regarding point #1, here's how my 430 system works: Connect an apple device and the stereo can control it, but does not download any files. Note that anything you downloaded from iTunes is in likely a proprietary format that only apple hardware can decode.
Files that you have in mp3 format can be copied from a flash drive. Everything must be in the top level directory, no folders or it won't work.
I have not had any success with pictures yet but haven't tried all that hard either.
