Most GPS batteries can last for a few hours on battery life, but continued usage and improper care can significantly decrease how long the battery can last between charges.
Download the Garmin Express app for free from the Garmin website, selecting either the Windows or Mac version.
The Windows version works on computers with Windows 7 and higher; the Mac version is for OS 10.10 and higher.
Keep the GPS unit connected to the computer as Garmin Express installs updates.
The updates may take several hours to install; check the on-screen time estimate to get an idea how long the process may take.
Note: Certain GPS units (60c(s)x, Legend/Vista/Etex (H)Cx, any unit released prior to the Colorado) have map limits.
