Come to think of it, most GPS manufacturers offer a GPS mounting accessory to satisfy your menu for some serious off-roading. But choosing such an accessory includes several factors:
Buttons: make sure that they are far enough from other ones so as not to confuse it when pressing on the specified button.
Sunlight: you could favor black and white readouts for motorcycle GPSs because it’s easier to read in direct sunlight.
Power: you must start worrying about the powering of the unit. Internal batteries are not suggested for off-road usage since it tends to loose contact at large bumps. Batteries all come with an option but take a look first at the connector. Make sure it is hard-wearing enough to handle staying connected at 75more mph.
Night time: make sure it has a backlight for night time viewing assurance. A nice glow will be sufficient and make sure the light isn’t too bright to cut down your evening vision. Also check if your headlights adjust to the brightness.
Mounting: you have to go with a vibration dampened bracket. Look at the base and check if it has a standard tripod mount.
Weather: sometimes unpleasant weather conditions can be a hassle. On rainy days, waterproof is best. But there are shells to cover it if you really need to.
Upsell: sure, manufacturers came with this ploy and they will try to get you to buy extra maps. I say, don’t pay for it. You can enter street addresses, Google maps and lay out directions in your GPS. You can survive all on your own.
Go for: costs less but saves more ample time. Make sure your wallet isn’t drained high and dry. Ensure no one steals it when you park your bike. A portable unit will be used more than a brick sized unit.
