Anyone with the av electronics nav tuner? My unit has been operating perfectly until recently, I can't switch between tv, av1, av2, and av3 inputs with the remote. The remote is working b/c when I press the "tv/av" button the screen goes blue, but then it just goes right back to the previous screen ( av1, blue screen, av1).

Any opinions?

I think there is a reset button on the unit, but I can't see if its a button or switch b/c of the way it is mounted. Anyone know how to reset it?

thanx
