Last week I bought a Cardo Scala Rider G4. Great unit and I have been keen to find a wireless UHF CB solution also. So I stumbled across the Wireless Pacific GTR which has a bluetooth option. Look here for details: http://www.rwaust.com/two-way-radio-uhf-professional/wireless-pacific/175-wireless-pacific-gtr-xu1 The staff from Radio Warehouse would have to be one of the best online retailers I have dealt with to date. Straight up they said that they dont know if the GTR would work with the Scala Rider g4 as it has never been tested. I took my chances abd bought the radio anyway, knowing that I could also use it for 4wd'ing stuff. Radio turned up the next day. Yesteday I got around to trying to pair with the Scala Rider G4, but it failed to pair. I emailed both Radio Warehouse and Cardo for tips. Helpful info from Radio Warehouse, and the following response from Cardo: Bugger, back to the drawing board. Maybe I can find a way to make it work.
