I have been using Garmin G.P.S. equipment for the last three years , and the only complaint that I have is regarding the lack of volume on the audio directions . I have tried a hearing aid type earpiece as well as a larger type fitted in my crash helmet lining . Both of these are useable below 30 m p h , but over that the wind noise renders them useless .I now see that Caberg are supplying a Bluetooth helmet for what appears to be the reasonable price of £150 . My question is - has anybody had experience of using a Garmin Zumo in conjunction with a bluetooth hemet and is it audible ?
