I am contemplating purchasing a Schuberth SRC System for my C3 Pro helmet. (Revzilla about $265) I never ryde with anyone (no one around who rydes) so person to person is not necessary. What I'd like to know is, if my GPS (which one would that be and I'll buy that as well) will blue tooth connect to the headphones in the helmet. And, could my Galaxy 8+ phone also be blue tooth connected to the helmet headphones. If they cannot connect and be useful, why buy the SRC system. I have a Garmin GPS on a holder center of the handlebars that speaks out loud but I can't hear it over the noise. And, it's 10 years old and best used inside my Sierra truck where it is much quieter.
