yeah, they don't change the case, knobs, or the plate with stations on it. It literally looks just like the original radio. You just flick it off and on quick to go from AM to FM. In FM you find a place on the dial with nothing going on, use the buttons like stock to lock in that position and when you want to use something other than a radio, just go there in FM and use your device with a plug. It would be easier as a bluetooth connection and I think they do them that way now (for more money). The only drawback is that you still have the AM radio dial, so you have to hunt for FM stations other than those you pre-program. If you want I can send a picture. All you do is send them a functional AM radio that fits/looks like you want it to...
