Not sure that if that will happen with the MP3 jack. Wouldn't cost much to try it and find out.Thanks
I was hoping to use the intercom system so that the radio volume would be muted when the GPS spoke (ie like it does when speaking on the intercom).
Any thoughts on tha (ie can I splice/Y into the intercom speaker output)?
I assume this is the thread you mentioned?Refer to another thread right here titled
"Wiring GPS into bike for sound"
His approach sounds perfect and I plan on trying it as soon as I get a GPS.
