have we got any cardo packtalk genius's on here I bought the packtalk duo and were great till I bought the r1200 rt lc now the units don't talk to each other how do I factory re-pair them so I can keep channel 1 and 2 with rider and passenger paired via factory pairing that keeps 1 and 2 open as I believe I have to pair helmet 1 to my bmw system to rider 1 channel 1 then pair sat nav to bikes system then pair rider channel 2 to sat nav and finally pair sat nav to phone that way the phone and sat nav use the bikes system and I can hear instructions then pair passenger to bikes helmet 2 so they hear shared music. but I can't do any of this because the duo pairing has stopped can I re pair them as factory or do I have to send them back any help would be appreciated regards Pete
