Chunkstar what name does your Nav 5 have? If its the original BMW name they can be quit long, sometimes this confuses the phone try a short name on the nav?
Sena 20 s
I Have tried everything I know of even cleaning the cache on my phone
My phone works to a alpine unit in van a honda crv Garmin and Android auto but won't with bmw nav just keeps dropping out
Sena is paired with nav was going from phone to nav nav to sena
Ok i tried wife's phone s5 not s7 and it dropped out too
So it's the nav ! Omg the hours I have spent
