I just purchased a '21 Freewheeler. I'm looking for the best helmet bluetooth audio for connecting to my iphone. I'd like to stream music, make/receive calls, use the nav apps, etc. I'd also like to talk to my husband while he's on his Road Glide. I've seen some posts for the Cardo Packtalk systems (https://www.cardosystems.com/shop/packtalk-bold/), but wondering if there are others worth researching or is the Cardo the best?
