I have acquired a Sena SMH-10 unit and installed it in my RF-1100 Shoei. The unit works as advertised with my 550 Zumo and iPhone 5s. The only thing that needs improvement for me is the Sena voice prompt volume. I have searched the manual, the Sena Help Forum and several M/C forums for how to increase the volume of the prompts but haven't found any info. Can this be done? If so, how? Any help appreciated.
