IDEAS, on mute

[stich626]

Hello, I have installed my clarion pro head unit, that I bought in 2004
into the truck, it has a mute lead that you'd hook to a car cell phone,etc
not gonna have a incar cell phone.. but do have a smart phone..
is there a bluetooth devise that can be hooked to this lead to mute as a call is coming in?
if not. anybody know of a switch that wouldn't look out of place
