Private Mode on the 30K allows you to talk with your riding buddies in a private conversation using the Mesh Intercom feature.
When connected together, a group of riders form what is known as a "mesh" which is self-organizing, self-healing and self-optimizing. No longer will you have to worry about losing half of your group due to a Bluetooth chain linked connection of the past. With Private Mode you can invite and communicate with up to 16 riders at a range of up to 2.0 km (1.2 miles). When riding with 5 or more riders, the Mesh Intercom will intelligently keep the group connected at a range of up to 8 km (5 miles).
