We were in Bryce Canyon last week and recieved a call from the animal shelter about 1 of our dogs. We were doing 45 mph with side winds and let it go to voice mail and played it back at the first stop thru the boom audio system and was crystal clear.
Than a few days later after leaving Arches National Park our daughter called to see what's up. At 70 mph with wind noise we told her to hang on so we could slow down, we use half helmets, but once below 30 mph or at stops the reception is clean.
Using iPhone 10.
Full helmet's would make it better but not what we have.
Ours is a 2015 but you would think newer must be better.
I had a call I answered while riding, came to a stop and while talking I turned the bike off. The call automatically changed over from head set to speakers but the microphone was still active.
Don't have any idea what is causing you're system to have static but wanted to let you have some feedback on how ours works.
