Has anyone had any experience with the new head Boss BV9351B unit? Trying to get my Samsung S20 FE G5 to use the hands free link with the new head. When I took out the OEM radio 6L3T-18C869-AC I noticed that it has 2 plugs in the back, one for the speaker wires etc. that are a match for the new unit. What is the second connection for on the OEM radio. The truck is not equipped with with a sub woofer under the back seat. The new unit seems to work just fine and it does not have a second connector.
