The export map will cover the current map view with tiles at 1:1 resolution.
The key thing to note here is that the GPS is limited to 100 map tiles at a time.
KMZ files placed in the [GPS drive]:\Garmin\Custom Maps directory will show up on the GPS.
There are two ways to export maps -- tiled and untiled.
But even across multiple KMZ files you can only have 100 tiles total across the entire GPS. 9) You can use Google Earth to preview the generated KMZ file and see what you have.
It will look less pixelated on the GPS since Google Earth resamples the map tiles and loses some quality.
If necessary, Topo Fusion will download missing maps, updating on the status at the bottom of the dialog. Just use the "File-Export View" command to get started.This tutorial describes the process of exporting any of Topo Fusion's maps to Garmin GPS units (currently Oregon, Dakota and Colorado support this feature). The Export View function will export maps for the area currently visible in Topo Fusion's map view. Pan and zoom the map view to show the area you wish to export.The feature is found in the "Export View" dialog in Topo Fusion. Select the checkbox for "Export KMZ to Garmin GPS." The options below it are now enabled.This is hands down the best way to get a GPS network onto a GPS for use in the field. I've found that the white background on Topo 4M makes the map more readable than the Garmin vector basemap (e.g. In addition I recommend 4M to cover more area (than Topo 2M) and also so that tracks you have loaded end up thicker and easier to see.You may want to add additional thickness to your tracks by right clicking on them in the map and choosing "Track Properties." 6) Aerial photographs are cool, but harder to see.
