Depending on what Garmin GPS unit you have, it will differ from GPS range to GPS range. (i.e. the procedure you will follow on the Garmin Nuvi will differ from a Garmin Montana etc.)
Your installed GPS Maps will always be listed under your Map information which is located under your settings / tools option on the GPS.
To use T4A GPS Maps on your Garmin device, you must disable any street navigation maps stored on the internal memory, as both cannot be active simultaneously. Ensure that only T4A GPS Maps is selected for navigation, or choose your street maps (e.g., Garmaps) if preferred. Using both map products for the same area can cause conflicts, so switch off the one you’re not using.
