I have a Garmin Zumo 450. I want to hard wire it to the motorcycle. How can I install this system on my 2008 Ultra Classic so that I can still listen to the radio/CD and when the GPS gives instructions, the radio/CD will mute until the GPS instructions are finished, and then resume the radio audio? Is it possible to hear the GPS instructions thru the external radio speakers, or just thru the headset? I have not found a dealership who can give me an answer on this.
Thanks
Steve
