Sorry to correct PGR but here is the deal (sorry it took me so long to respnd but had to find a paper to be accurate) Garmin makes both the Road Tech (RT) and the Zumo. Harley required a special tone in theirs to work with thgeir boom audio system, so the zumo does not, will never have that tone. You can use a 3.5 wire (two male plus like for an ipod) plug one into the 3.5 female on the zumo/RT harness and the other into the radio aux port. when you put your radio into aux you will get the zumo now. If you have a 665 you will have xm abilities (xm radio, traffic, and weather).
Now for the stereo switch, in the forward position, you get audio, bike-to-bike, comm/intercom will come thru rider and passenger headsets, middle position-audio will be heard through the vehicle speakers, bike-to-bike comm/intercom will come thru rider and passenger headsets,back or down position-audio, bike to- bikecomm will be heard through the vehicle speakers, Intercom will come through the rider and passenger headsets.
The NIM (navigation interface module) is not what it is supose to be, they(Harley) are working on an updated version. If you want bluetooth check out the forum here for the HD Bomm- it works!
So plug your zumo into the aux port and put your radio on aux and you will get the nav through the radio, turn the speaker switch to the position that you want the sound to come through, and you are there. Remember that the Zumo 660 does have the ability for you to down load music onto a micro SD card and put that in the battery compartment so you have the music you want and you can play that and it will mute the music when navigation instructions are coming out, then go back to your music.
More questions, just holler! Don't forget to register your zumo with Garmin, operation software updates are free, mapping if you register within the first 90 days you will get a free map update, after the 90 days you can do a one time update for about 50 bucks or do the life time, allows up to 4 times a year for the life of the unit for 90 bucks.
