Garmin GPS units are made for a variety of purposes. The company offers GPS units for truckers, auto drivers, backcountry hikers, aviation and nautical purposes. These GPS units are powered by batteries, AC outlets or through a vehicles cigarette lighter or battery. If you have a need to get to the inside of the Garmin GPS unit you need to "crack" the shell and casing. Use caution when doing so; check your Garmin warranty as cracking into the GPS case may nullify the warranty.

Things you need
- Small optical sized Phillips screwdriver
- Small optical sized flathead screwdriver
- White paper
- Flat work surface
Spread white paper over a flat work surface. Use the white paper as contrast to make finding any dropped screws easier.
Unscrew any retaining screws on the back of the unit -- these are typically Phillips head screws. Unscrew over the white paper. Place the screws in a safe location once removed.
Slip the flat end of the flathead screwdriver -- use one of the smaller optic style screwdrivers -- into the crack along the edge of the casing. Gently pry until the casing pops open. The GPS units have a rubber gasket to make the unit water resistant. Take care not to rip the rubber as you insert and pry.
Pull the two casing pieces apart to expose the inner workings of the now cracked Garmin GPS unit.
