Does anyone hear a sound coming from the right rear side when changing radio station presets (stock ML, no mods)? It sounds like the DVD in the nav system spins when I change the radio. Only for a second or two, bur clearly audible and never again until I change the station. Never noticed it in my ES w/ML and Nav.

That is the antenna automatically lengthing or shortening to achieve the best length for the frequency of the radio station to which you are listening.

Johnny I thought the antenna moved up or down when switching from AM to FM I was not aware that if you were on FM that the antenna would raise or lower from FM station To Fm station

Yes

nope. it moves when you simply change stations. give it a try

I believe it has 2 FM positions, and will change when you go from a low frequency station to another FM station in the higher half of the dial. I do not think it changes length when you change stations that are close to each other on the dial (but I might be wrong on this).
