Hi, We have bought 2 AOM bluetooth helmets which do not appear to link together for rider to pillion intercom just for mobile phone etc. I have contacted manufacture for help but no response! We already have the original Starcom1 system set up on our bike and I know there is a dongle that will link both together, the wire3, but at over £100 each & need 2 of them it is a little out of our budget. Does anyone know of an alternative idea to link the 2 bluetooth helmets together please? Many thanks H
