I'm looking for cheapest way to get IFR WAAS into my plane and am considering a GNC-420 unit with a recalcitrant flip/flop button. Can any one confirm that these units have an input for remotely switching com frequencies, like a button on the control stick?
Incidentally, what would be a realistic good price for a GNC-420W or maybe a GPS-400W?
