How do you get GPS directions to come over RTL Speakers?

[stebrock]

I installed a Zumo XT on my bike and followed all the input I could find on how and what to pair.
I have my phone paired to the GPS and no issues.
I have the GPS paired to a Bluetooth adapter in the glove box and I can play music that I downloaded onto the GPS, but I cannot get the GPS to play the turn by turn directions over the bikes speakers. If I am playing music the music comes over the speakers but when the GPS plays directions the only way I can hear it is thru the small speaker on the GPS. The same thing happens even when I am not playing music, the GPS directions only play thru the GPS speaker.

Dazed and confused and looking for some help not criticism.

Thanks

Did you try my setup?
