Mike......thanks for the post. Went and did the side-by-side for the two units.....sure enough, they're virtually identical in features (but you knew that , esp the ones I was concerned about. I suspect you're dead-on correct about why they discontinued it (though you can still buy new ones through amazon).....dammmmm marketing bs. I'm sure I'd be happy with either one.....just a little poorer since I had earlier pulled the trigger on the zumo.
