A:Answer You know... as far as I am aware, I don't think the system supports A.M. I think it only does FM. Don't quote me on this. If you *can* toggle it to A.M, I'd love to know how, as looking in the manual isn't saying anything, and when I hit FM mode on the remote, it doesn't cycle to A.M. So, yeah, I don't think it can be done. Plus, I only saw an FM antinna in the box, no A.M antinna. So, yeah... Sorry I couldn't be of more help, but I hope this at least kind of gives you an answer, even though probably I'm sure, not the one you really wanted. LOL! Take care, God bless, and if you celebrate, then you and your's have a very very happy Thanks Giving!
