Extract the following ZIP files to access the application files to install the application on your Windows computer.

• Base Camp
This is Garmin's flagship mapping application. It reads GDB(Garmin), GPX(generic), TPO(National Geographic) and KML/KMZ(Google Earth) files. You can purchase topo maps from Garmin.

• Mapsource
This is an older Garmin mapping application which I still use regularly. Some of the path creation functions are much easier for me to use. It reads GDB and GPX files.

• Free NV Topo Map
This is a map installation application which was a free download from https://www.gpsfiledepot.com/. It is not as high a resolution topo map as your high resolution maps from Garmin, but it is free. There are many other maps available at gpsfiledepot. Once installed the topo map is accessible from the Garmin applications provided the mapping applications were installed first.

• One of the California maps I use
This map is one of the two California maps I use. Switching between this and the next California map allows me to see different features.

• The other California map I use
• The trails registered with My Trails
This has only trails registered with "My Trails." Switching between this map and any other maps allows you to see possible trails. This does not mean that there might still be some trails that have not been registered with My Trails.

I also have used TOPO!(National Geographic) which I have had for many years. I do not use it as much anymore since Garmin's software is free and even easier to use.

Most often I use Base Camp and Mapsource with Google Earth, which is free from Google. Sometimes I can see in Google Earth the trail or way that looks best and create a path, which I can export as a KMZ file. I can read the KMZ file in Base Camp to work with it there. After anchoring the path to elevation in Base Camp I can export it as a GDB file to work on in Mapsource. The results are saved back to GDB and read in Base Camp to be printed in the format I like. It's a little cumbersome but free. I'm cheap!
