Hello Everyone! I would like to ask for your help before I purchase a Sena system, I'll most likely get a 30K for myself, but my wife is not interested in getting one for herself since she just occasionally rides with me. What lower models do you recommend I'll get for her that will allow her to connect with the 30K easily? She'll just ride at the seat behind me. Even entry level models you'll suggest would be most welcome. If it will allow her to connect to an extra comm system or 2 would be a bonus but most importantly just to my Sena (most of the riders in my group uses 20S). Thank you everyone
