I give up, i need help. does someone know the color of the wire or wires that mutes the radio & allows the voice to be herd on the speker from the navi. brtter yet does anybody have the wiring diagram. I MUST BE BLIND.

i am trying to instal a alpine 9835 into my car and keep the navi voice. and would i hook that wire to the phone mute on the alpine?

Sorry if this is something yall have gone over before.

 

yes hook it up to phone mute

as long as the navi gives out a ground when it speaks
