We are 4 motorcycle riders that like to do trips together. 2 of us use the SF4, 2 of us use the 20s. Setting up intercom where we can hear all of us is challenging, but it worked with a 4way intercom setup. But! - One of the SF4 user is the one with GPS. And we never managed to have a working intercom with the 4 of us AND still hear the GPS instructions. - The other SF4 user is not able to still have connection with her mobile phone (Samsung) - One of the 20s user got muted the second half of the journey. The connection was still there, because she was 'C' and the other 20s user (D) was still able to communicate with A and B. So, long story short: How do we setup a group intercom (I think that is better than 4 way intercom) with 2x SF4 and 2x 20s AND manage to hear GPS audio for one SF4 user AND manage to keep phone connection for the other 3 riders?
