Im think i am having the same issue. Every time i turn the radio off either the ipod wont go into axess mode or the radio wont recognize the ipod and nothing will happen when you press the media button. It works after i unplug and replug the box, but this is very annoying because it happens everytime. Did you ever get yours to stop?
wow...sorry i missed this post.
i moved my axxess box to the area next to the shifter and it seems to be working better. I think thats a more stable spot for it. hard to know for sure though.
