Hi Guys,
Bought a Garmin Nuvi 550, I currently have it hooked up with through the audio in/out.
I want to be able to "Key" the mic so that when the GPS gives audible directions
the "keying" of the mic will let the other riders hear whats being said along with me.
When I key the mic now, I can't hear whats being said and nobody else can hear
anything...... What am i doing wrong? I know it's possible as I think somebody else
has it working from a group ride I was on last year.
