My wife and I are now riding places (each on own bike) but there are a couple of things I ant to do that I'm not sure how it works.

1. What stuff do we need to talk to each other while riding? I see some companies, but I'm not clear on what is exactly needed.

2. I want to install a GPS on my R1200s, I've narrowed it to the Zumo 550, but again I'm not sure since there are so many options out there.

Any and all advice is appreciated.
