Note: You'll need version 2.0.9 or higher to load custom maps. Open Garmin BaseCamp (all screenshots from version 4.3.4).This also causes a variation in how you select maps this variation will be covered in this tutorial. For older units it will have to rebuild the entire map database you've selected each time. For newer GPS units (Garmin Colorado and newer including Dakota, Oregon, Montana, and 62 series) the program will allow you to manage maps very easily/quickly. When loading maps onto your GPS Garmin BaseCamp is the preferred program. Loading The Maps With BaseCamp and MapInstall on a PC Warning: If you bought a micro-SD card that contains maps from Garmin DO NOT overwrite this card, use another card. PC: Use BaseCamp/MapInstall To Load Maps.This tutorial was updated in July of 2014 for the updated PC process.

This how-to will detail how to load additional maps to your GPS unit with either a Mac or a PC. These receivers can still have maps loaded to them though in addition to the maps that already exist. These days many of Garmin’s new GPS receivers contain built in maps, from the nuvi series with road maps to the Colorado and Oregon with topos.
