Right according to the iphone app store description it should work with the RV760.... SOOOOOO close... Unfortunately it is not in warranty... I wonder if I have to flash it fully to a 760 to get the smartlink to work.... scary lol... I agree that its probably the unit, thats why I was trying to cut my losses and pay for the smartlink traffic... The first year I owned it I flew to other trucks a lot and didn't bring it with me... So I really didn't think/notice that it had a problem... They were cool with swapping out the traffic/charger cable... my own fault I guess...
