I have had the GPS for a while now but since November, I have been using a Midland GMRS radio to communicate with riders, and especially my kids, in our riding group. Wonder how many of you are doing the same thing? Our longest distance is 18 miles so far in an open, shallow valley with line-of-site at El Mirage in So. Ca. I was amazed because my wife was at her brothers house, in the house, when she turned on her radio and inturuped our conversations. Also wonder if any of you have seen some of the Bluetooth stuff out there that is compatible with GRMS radios for dirt bikes. I think my WR is starting to turn into a electronic machine.
