Do you know of any external microphones that will work with head units in 2015 Peterbilts? Truck has nav and bluetooth phone but as with most head units speaker is too far away from driver and callers can't hear me.

I believe there is a plug on the back of the radio for just that. You would need to check with the service center for Pete to see if they know. If so it would probably be a peko brand from Pana Pacific
