Hi all

I have been using a Sena SMH5 lately to listen to music, sat nav and using the phone(is this illegal?) I know a friend of mine got a Bluetronic. We are going on a long trip soon and it would be nice to to be able to talk to each other. But, will they link being of different makes? Anybody tried?
By the way, we can't try it out, we are in different countries right now.
