Does anyone know what that phone **** on the radio does? The manual just says it turns it off and on. Okay? Great, is it some sort of blue tooth function?

 

First of all, it's a button, not a **** second, afaik if you had sync it would be used for phone functions within the vehicle. If you don't have sync, then it does nothing, feel free to push it if you have nothing better to do.

Actually it does do one thing if you don't have sync - it makes the radio display say "no phone" or some such nonsense

 

Usually it mutes the radio. Well that's what it does on my f150. Haven't pressed it on the stang yet
