A year ago, I bought a Garmin Quest for a trip to Canada during the Christmas holidays. I planned on using secondary roads once in Canada to save time. Once the Quest got me to Port Huron, MI, I left the main hiways and set out on Ontario’s Concessions, Side Roads and other rural roads to Proton Station (you know where that is, right?). Inasmuch as the post card sized secondary road signs were snow covered by the plows, I was fortunate to have the Quest. I never made a wrong turn. It provides clear voice prompts and plenty of advanced warning for upcoming turns and route information. At night when it was snowing or road signs were otherwise illegible, the Quest kept me on route. Oh, and I easily found gas, etc. without having to explore dark towns at night. One day, I needed some work on the car (heater went dead…Brrrr). My Quest routed me to the nearest Ford dealer.
When on the bike, I merely put it in the tank bag and leave it on. If I come to a point where I need some help with directions, I snatch the Quest out of the bag, hit the display button and I have everything I need to keep me on route.
The Quest does have compass and elevation capabilities as evidenced during recent travel on a commercial aircraft. The elevation was within a few hundred feet and the compass was right on track.
I am a bit near sighted and use glasses for reading only. Therefore, when driving, I rarely refer to the visual display but rely more on the upcoming turn information which zooms in to large, legible detail on the Quest display as a turn or way-point is approached.
But, if you rely on visuals, you may want a bigger display.
Battery life on the Quest is adequate for a couple days of use. Memory on the new Quest II is excellent and substantially better than mine. However, I have found my older model adequate for travel anywhere on this continent.
Also, I have found Garmin’s tech support to be very good.
If you want a feature packed GPS that is small, compact and high performance, the Quest II is a good choice. If you want a large display along with plenty of performance and features, then the 276C is the choice. I would look at available space in your bike’s cockpit before choosing.
As for mapping and routing, you can make a new route on either unit or use your PC and download to the GPS. To my knowledge, Garmin’s software is not compatible with other mapping programs.
The backlight is programmable to go to dark (user selectable time) when running on batteries to conserve battery power on either unit. However, the unit keeps navigating and maintaining all the route details even when the backlight is extinguished.
There are a plethora of features on these GPS units. I would go to the Garmin sight and download the operator’s manual for the units of interest and determine what features you need, then make your choice.
You’ll never need a paper map again.
