angela,
my FMTV works great, it's coming up on 4 years now.
this is what you need to do if you cant' reset it... turn on the FMTV and press FIND button that will rotate the mast to whatever direction it's prgrammed to.
loosen up the dish and manually turn it till you get the strongest signal, then tightened it up. that's it.
the motor runs all the time, in very small increments right and left, so if you hear some buzzing and very minor movemnet, it's normal. More than that and you have some interference... Ideally you need to install it far from large metal objects, I thinks yours is pretty close to you RV style AC on the Hard top, isn't it ?
it's a no frill unit but i like the simplicity. fully stabilized antennas have come down in prices but they're more complicate, my neighbor installed a sea king and has had a number of issues with it.
