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

I don't have any points on the bluetooth, but for a switch the 1st thing that comes to mind is one you're not using such as wipers or even the high beam, or even wiring the cigarette lighter to mute it when pushed in...but then again, that's further away than the radio so maybe not such a smart one.

i guess it depends on the power/hookup
but i use a small switch beside the radio up is on no key
down is with key
middle is off
not a mute but it's small to hide
