how to integrate a dash monut GPS with car stock FM radio and speaker system? Answered
I like to use my car speakers with my dash mount GPS. Is there anyway GPS announcements can be made thru the speaker system while the radio is on playing either by fading the music or by temporarily interrupting it.. The GPS has a headphone jack output and a USB port and it is bluetooth enabled. I am thinking that a sound activated FM transmitter with an integrated sound activated switch might do the trick. Any suggestions or solutions?
