Howdy.... I'm new to forum (and mapping gps). I found this hunting for maps to install and simply moved on when I read this: "download the .tgz file from the link at the top of this page, unarchive it into the resulting .tar file, then unpack that to a .gmapi file. This file can then be installed into RoadTrip with MapManager and onto the GPS receiver with MapInstall.".
3 extensions i dont know, and 3 programs that I don't want to install on my computer. After some thought, I decided to ask if this was a available, or could be made available for people like me who would enjoy these maps... But don't want the mess. (or doesnt need all those states) How bout this?
Garmin Washington state trails 1.71 download: .Kmz Or .img
By state, the files should be tiny. No compression needed. Just download, drag, drop, enjoy.
You're quoting the Mac instructions, so can I assume you're on a Mac? If so, I'm not sure if Jon can help you, so I'll offer some thoughts.
This isn't as hard as it sounds. You don't need to know anything about the file extensions. However, you DO need to have MapManager and MapInstall installed on your Mac. These are Garmin programs and are required in order to install maps on a Garmin GPS receiver. So get them: http://www8.garmin.com/support/collection.jsp?product=999-99999-06
(one download for both items).
Once you have those installed, the process is really this easy:
- Click the link for the mapset you want and save it on your computer.
- Double-click the downloaded .tgz file; this will unpack it to a single .gmapi file.
- Double-click that. MapManager will prompt you to confirm that you want to install this mapset on your computer (for use, for instance, in BaseCamp, and necessary for installation to the GPS receiver). Confirm by clicking "Install." When that completes, click Quit. You can now delete the .tgz and .gmapi files.
- Connect your GPS receiver. It should show up in the Finder.
- Open MapInstall. When it detects your receiver, select the mapset you want to install from the popup; then select as much or as little of the geographic coverage as you want to install on your receiver; and let 'er rip.
I'm not sure how Jon could make it any easier, and having to download (and then install) separate mapsets for each state would be a real pain and waste of time, when it is trivially easy to pick your geographic region from within MapInstall.
