One of the new TWO members, Renegadebiker24 is having audio problems with the SENA SMH10 and GP10 combo, so I thought I would run through all the different combinations of various setups since I have everything here, and see if we can’t get to the bottom of things. I did. Bottom line is the GP10 only like the 20s or later generation of systems. I have filed another support ticket with SENA and included all the data. We’ll see what happens.
