He knows his stuff. He sorted my RT. But I still couldn't work it, not his fault. Case of pressing right buttons in right order. I couldn't. So silence all the way. Ended up just not bothering.
2 n arf hours later everything appeared to be sorted, blueteeth, paired to phone, paired to helmet, paired to system blah blah blah, but the sound would not come through to the helmet.
My mate went away scratching his head (getting splinters).
So for the time being it's a case of having the speakers on the bike do the job (when i want or need verbals)
Why oh why in 2020 do the geeks have to make it so effing hard to do something like this. Surely if they are that smart they would/could make it easy for a NORMAL

Then again if they did they wouldn't look so smart and command their big bucks salary's eh.
