Answers To Our Most Commonly Asked Questions
Do the snowmobile trail maps have just the main corridor trails?
The snowmobile trail maps have the main corridors plus club level trails. If it’s a groomed trail, it will be on the trail map. We don’t currently have every mile of trail on the maps but that is our goal. Corridor trails and snowmobile club trails are identified by color.
How are the ATV and Snowmobile trail maps loaded onto the GPS?
During the checkout process, you will be provided a “Download” link for your trail map. When you click the Download link, the map installation program will be downloaded for you to run immediately or save to your computer for future use. When you run the installation program, the trail map is copied to the GPS using a USB or other serial port.
How is the trail map updated when the trails change?
When snowmobile or ATV trails change, a new version of the map is released. When you initially purchase a snowmobile or ATV trail map from the website, you create an account where your map purchase is saved for 1 calendar year from the date of purchase. You may login to your account at any time and download the latest version of your GPS trail map.
How often is the snowmobile trail map updated?
As long as the trails can be ridden, we will be collecting GPS data. We will typically release an updated version every 4-5 weeks or 2-3 times per season.
How does a GPS hold up in cold weather?
Garmin hand-held GPS’s and certain hybrid GPS’s are rated for temperatures down to -4 degrees F. We have operated the Nuvi 500 down to -20 degrees F. Most of these ruggedized GPS’s are also waterproof (IPX7).
Will the GPS trail maps work with any GPS?
Our GPS trail maps are only compatible with Garmin GPS. The trail maps are compatible with any Garmin GPS that has the ability to “Add Maps” or that have an SD or microSD card slot. Consult the Garmin website for specifications about your GPS model. The following Garmin models require that MapSource be used to install the map to a blank microSD card (our preloaded microSD card may not work). These devices do not have internal memory and have a different way of communicating with your computer.
Can I use my automotive GPS on my ATV or snowmobile?
Yes you can but automotive GPS’s are not ruggedized and care should be taken to keep them dry and warm. An automotive GPS is typically rated to operate down to 32 degrees F and are not waterproof. Many of the lower-priced automotive GPS units do not have internal memory for storing supplemental maps and require the purchase of a microSD chip.
Will the trail map overwrite the street maps on my GPS?
Our ATV and snowmobile trail map is a transparent overlay that shows on top of the streets (you see both at the same time). You will have the option to turn off the display of one map or the other after the trail map is installed using the Map Info screen.
Where can I buy a Nuvi 500/550 or other rugged Garmin GPS?
The best way to purchase a ruggedized Garmin GPS is on the Internet. There are many competing resellers. A Google search for the model you are interested in will return a number of choices. The Garmin website www.garmin.com is best place to research the different types of GPS’s and compare models.
How do I mount a GPS to my sled or ATV?
There are three elements to mounting your GPS. First, you will need a cradle designed specifically for your GPS. A cradle is custom designed and must be the correct one for your Garmin model. Second, you will need to decide where to attach the cradle to the sled or ATV. The handlebars can be used, a flat spot on the cowling or it can be mounted to the windshield. Select a location that provides easy viewing and not likely to vibrate significantly. Cradles and mounting hardware manufactured by Ram Mount can be purchased on the Internet. Lastly we recommend that you hardwire the GPS to a power source. Wire kits are available for direct wire to the battery or cigarette lighter type automotive accessory plugs if your snowmobile/ATV has one.
How do I tell what version my trail map is?
The trail map version is listed with the map on your GPS "Map Info" screen. Consult your Garmin Users Manual for how to navigate to teh Map Info screen.
Why do the trails on my Nuvi 500/550 disappear when I zoom in real close?
Some Nuvi models, including the Nuvi 500/550, have a known issue where the Garmin provided base map displays over the trail map when you reach a certain zoom level. To fix the problem on older versions of our trail map (before V3.00), disable the “City Navigator” map from the "Map Info" screen. Our new version 3.0 with auto-routing has eliminated this problem.
How can I notify GPS Trailmasters when I ride trails that are not on the trail map?
If you find you have ridden a trial that has changed or is not on the trail map, you can send us the tracklog and we will update the map. The tracklog, known as the trip log, is usually stored in the \Garmin folder on your GPS. Connect the GPS to your computer. Use My Computer to locate the GPS drive. The trip log will be a .GPX file in the \Garmin folder or possibly the \Garmin\GPX folder.
What is the benefit of the microSD chip?
The microSD chip provides a convenience of plug-n-play maps. No other installation is required to get the GPS trail maps up and running on your GPS. The installation program should still be run however to install files onto your computer that are used to get your free map updates.
Does the GPS give the distance in miles to a destination?
New with Version 3.0, you can specify a location and the GPS will calculate accurate distance and arrival time. The auto-routing feature will also provide turn by turn directions.
Does the GPS automatically plan a route from one location to another?
Our Version 3.0 does have the “auto routing” feature. However, the auto route algorithm does not know the conditions of trails. You can Detour around poor trail conditions or pick another trail and force the GPS to calculate an alternate route.
Why won't my GPS auto-route across a lake?
Our Version 3.0 “auto routing” feature does not know if lakes are safe for travel. Your GPS will recalculate your route if you choose to cross a safe body of water.
My auto-routing feature is unable to calculate a route.
The auto-routing feature can get confused when there are multiple road and trail networks to route over. When you are out on the trails, disable any Garmin provided street maps to prevent the auto-routing feature from using them.
Can I have an ATV trail map and a snowmobile trail map installed on the GPS at the same time?
First, we do not recommend combining the ATV trail map with the snowmobile trail map because it will be too cluttered and too difficult to tell the two apart. You can have both maps installed seperately on the GPS if you have both internal memory and a microSD card, however this assumes you don’t have any other third party supplemental maps on your GPS.
If you purchased both an ATV trail map and a snowmobile trail map and have a microSD card slot, install the ATV trail map to one microSD card and the snowmobile trail map to a second microSD card. Optionally you can install the snowmobile trail map during the winter and then install the ATV map during the summer. Repeat each season overwriting one map with the other.
