Updating my gps maps
In some cases, you may be able to opt out of some updates, such as maps.
Keep the GPS unit connected to the computer as Garmin Express installs updates.
The Windows version works on computers with Windows 7 and higher; the Mac version is for OS 10.10 and higher.
Your device may be up to date if you docked your device frequently or recently purchased it.
Once installation completes, launch Garmin Express. The app should open on its own at the end of the installation process; if not, select the Garmin Express icon to open the app.
Once the program opens, select your GPS device from the options offered on screen.
Downloading maps for the wrong system will do nothing for your GPS maps.
Also, make sure that your GPS has the capability to be connected to your computer, otherwise you will only be able to get your maps from a map disc or through the unit itself, and not for free.
There is other software available for varying formats, some specific and some open for all systems to use.
