Hi All just joined the site need help with swaping ntg 2.5 audio 20 to a ntg 2.5 comand problem is with both units being bluetooth i thought there would be no messing about with fitting other mic's etc. After swap was done and phone call is made i can hear them but they cannot hear me i thought this was only a problem with older none bluetooth audio 20 when fitting 2.5 comand also i have the radio problem no Am signal witch is strange again because the car already has the twin fakra antenna.
