how to resolve slow download of map update issue

https://garminsmapupdates.com/unlock-garmin-maps/

Like paper maps, a country or region is split into several smaller maps. All Garmin maps have the extension '.img'.

Before these maps can be used on the GPS unit, the maps have to be bundled in a single container. Usually, Garmin own software MapSource bundles the maps and stores it in the Garmin folder of the unit's memory.

Garmin supports the following container files:  gmapbmap.img Typically this is the preloaded base map.  gmapprom.img Typically this contains the preloaded detailed maps.  gmapsupp.img Typically the maps uploaded by Garmin MapSource.

 Not all units support the same container files. To find out if

your GPS unit supports these, just rename one and see if the maps are still visible. For some models the latest firmware upgrade removes the naming restrictions of the container files.  Each map has a unique 8 digit number identifying it and mapsets can be identified by their family id.  Individual maps cannot be viewed or selected directly from MapSource. For this a mapset has to be defined. Some of the free maps provide an installer that directly installs the map into MapSource. If such an installer is not available, the tool MapSetToolkit can be used to create the mandatory files for MapSource.  As an alternative to Mapsource, sendmap, mapupload or QLandkarte can be used to add single files into one aggregated file.
