Thanks gents for the info ... and apologies again for wrong info .
Everything has been flashed and ready to go Wednesday for the Harley Days Trip ... still have to experiment with headset settings ... I reckon the Vox was set too sensitive as the Voice activated intercom was activating and cutting in and out while music was playing all the time riding along when no one was saying anything ... I figured the wind or possibly even the pipes was setting it off .
Turned intercom off and when got home worked out where the Vox settings are as well as some other settings and adjusted them all ... will check tomorrow and see if there is any difference .
I must admit before they flashed the boom box and headsets I thought the headsets by themselves were nice and easy to use and understand ... I would prefer the PTT push to talk function but mine doesn't seem to have it , at least it isn`t where the pic shows on right handle bar controls .
All part of the learning curve .
