Also be advised if you hook up with more than 3 friends they will need to be mesh capable. The old 20s could do 8 i think on regular Bluetooth. And sena mesh is not compatible with packtalk mesh. And neither packtalk or sena work well with my garmin 595 gps! If you want the phone and text message to show on the garmin you loose the voice commands on the packtalk. Did not have the sena long enough to check that with the new sena.
