Looking to get a GPS for my Ultra and for car. As far as I can tell, if I want to be able to connect via my AUX In on my H-D radio, I have just the HD Road Tech & Garmin Zumo's to choose from. Since, with my eyes, size matters I'm looking at the Zumo 660 or 665. Don't really need XM Satellite radio so kinda leaning to the 660's. The Road Tech Zumo 660 ($739 CDN dealers, $650 US dealers) from H-D is about $80 more here in Canada as compared to the Garmin model ($650 CDN). Difference between the two is HD's has the dealerships programmed in, AC charger adapter but no handlebar or fairing mounts (sold seperately) while the generic Zumo 660 comes with handlebar mount, car mounts, wiring for motorcycle power supply and cig lighter adapter. The HD fairing mount is another $46 CDN or $36 in US. The handlebar mount is about triple the fairing mount price. Also can get a Garmin Zumo 660 with lifetime map updates for $50 more ($700). Harley doesn't seem to offer that option and, if the map updates are from Garmin, the lifetime updates are an extra $90 US. Still juggling in my mind which would be better suited to my needs. I carry the HD Road Atlas so having the dealer listings isn't that big a deal but would be nice. On the other hand, for about the same price as it'd cost me to pick the Road Tech up the next time I trek down to N.D., I could get the Garmin shipped to me from a Canadian supplier. Anyone have any experience with either GPS or know of a current automotive model GPS with a headphone jack? Blast.. the more I type this thread the more I'm convincing myself which one I want.
