Okay- So, my new 2015 RT-Limited can play the sound of the GPS through the bike's speaker system. ONLY if you have the Radio on and if you tune it to an OFF STATION you sometimes get static as the radio is trying to catch radio signals. I decided I didn't like that so....

I synchronized it to work with my Sena-Helmet system. I have tried to:

1.) lower the volume settings within the Garmin 590 itself.
2.) lowered the volume on my Sena

Here are the issues:

If I lower the volume on my Sena then when it restores my intercom I can hardly hear my wife talk to me.

Otherwise- the darn instructions STILL blast my head so bad I cringe!

What is the trick to getting a nice- volume level from the GPS to the Sena without it blasting my head.

I mean how hard can this be? Really?

Anyone with similar experience who can give me a clue!

Thank you!
