However comparing Randy's images below, I'm having a hard time seeing if the trails shown are the same.
Am I wrong?Ī buddy of mine who is into adventure riding says the 24k West is the way to go. It only shows the main streets in my town, so I assume it's that level of detail for everything. Just looking at it from my home, there is very little detail. I assume what comes on the Montana is the 100K.
The topo maps are useful when working on tracks on your computer. The contour lines and all the other detail on a topo make it harder to see your track at glance and if you have to look harder you're gonna crash. There is no way I know of to turn off the contour lines on a typo map. You can run the screen full bright all the time which gives the best view. With the powered cradle wired into the bikes 12v supply batteries are a thing of the past. Montana along with a "rugged powered" cradle is the best for motorcycling, dirt and street. City Navigator is the best map when riding with your GPS device. There are no turn directions only a line on the map and if you leave the line then get back to the line. This is basically connect the dots and follow the line. "Tracking" is what one does to navigate off road. The device then gives you turn by turn directions. Auto routing is was one does with their smart phone. For dirt riding this is no big deal as none of the maps will auto route effectively on trails. I think you can still find a 24k map on line for free but it will not have auto routing capability. There are no limits on how many layers (or zoom levels) a Garmin map is required to contain.Ladd - what is it that you don't like about the 100K vs the 24k? Changing zoom settings on a GPSr simply tells the GPSr which layer of the map you wish to display, and it will scale that data on the screen, up or down, as desired, until the next zoom level (or layer) is selected. Garmin maps also have a layer that remains visible at all zoom levels, regardless of GPSr settings. For example, there are Garmin maps that display BirdsEye imagery at lower zoom levels and traditional vector data at higher zoom levels. Garmin maps do have 'different levels' of data, one for each zoom range, and a map maker can compile their maps to show any data they desire for each zoom level. I'm not sure why it would fail to draw the map at those specific zoom levels, but that is what's happening. The issue you are having would not be from basecamp or the Topo US 24k map, but the GPS itself. The map data doesn't change, but the GPS might hide or show different pieces of data based on zoom level depending on your map display settings. They are vector graphics (except for custom maps, which are usually rasterized), and the zoom buttons do just that - zoom in and out. Maps don't have different "levels" built into them.
