Autocom BT-203 Interface for Bluetooth Module

This only applies to the pre 2009 systems where you want to connect a phone and or GPS via Aux 2.

The Aux 2 automatically mutes the incoming audio which is detrimental to any two way conversation.

Therefore using the BTM-O2A is the preferred method of connecting to phones and GPS’s as you cannot get the same result with part 4066 due to the muting function on socket 2.
