Haybaler- Berkeley or Hollister?
Cycle Gear is everywhere and I believe Road Rider-SJ is closed.
Sena gear works for me. Can hear music and phone in my modular/flip helmet. Has FM native to unit and with Bluetooth can access your phone for tunes and calls.
Most important on a cross-country ride was FM radio. Listened to local radio stations for tornado warnings. Very, very valuable.
Additionally, Bluetooth linking to google maps for directions. When you space out, enjoying the countryside and tunes, nice to have that voice nag at you to turn at the next exit.
Since I was often riding 10+ hour days, used a solar USB battery charging device. Mounted on handlebars, ran that to phone to keep the music and directions powered. Sena lasted quite long and only occasionally had to hook it up either on a break or long-cord connected during ride.
Install is easy if you are decent at arts-and-crafts type projects. I'm not and had Road Rider salesman mount it.
