I take that back, I do have a 3.5 audio thingy, was hidden under a flap on the bottom of the unit, have to get used to these Zumo's.
Just finished wiring the Garmin in the left side cubby now for a 200 mile trip to a town I have never been to before, will be my first time w/ a gps on a bike.
You will love it. Just be careful, they can be distracting. Last fall I finally put one on the bike. I'm still a paper map person but slowly starting to get it. My probolm is I'm old enough to still not trust the electronic stuff. Ya I still have a pouch with paper maps in the side bag.
So, you're good to go with audio to the speakers?
