i was thinking about a nice quick way to 'Hush' the playback. in the emplode config, you can select what happens when the interrupt wire is triggered (when input is either 0 or 12 volts) by a phone ringing for example. i dont have a phone but what if i connected a wire to that lead on the riocar and added a switch to act as a phone ringing to trigger the automatic 'hush' mode? what woulld be the best way to acheive this? i thought about remapping a button on the player but i'd rather use those buttons for other functions.
