That naming convention applies to other units too - (certainly the Nüvi 310 and StreetPilot C510 that I own). Suppmap = gmapsupp.img (SD Card drive only) Suppmap1 = gmapsupp.img (nuvi drive only)Ĥ. Nuvi internal (diagnostic utility) OS map namingģ. gmap3d1.img (7x5 only) nuvi drive only (secondary 7x5 3D Buildings map), configurable as a supplemental map rename desired mapset to gmap3d1.img gmap3d.img: (7x5 only) nuvi drive only (default 7x5 3D Buildings map), configurable as a supplemental map rename desired mapset to gmap3d.img gmaptz.img: (7x5 only) nuvi drive only (default 7x5 Timezone map), configurable as a supplemental map rename desired mapset to gmaptz.imgĨ. gmapbmap.img: (7x0/7x5) nuvi drive only (default basemap), configurable as a supplemental map rename desired mapset to gmapbmap.img, NOT selectable and does NOT show up under installed maps (Tools/Settings/Map/Map Info) but may be visible under Tools/Settings/System/About/Basemapħ. *Note, when using the following default system maps as user maps, you'll naturally lose their default map attributes.Ħ. gmapoem.img: (7x0/7x5) nuvi drive only (OEM mapset), user accessible, cannot be unselected from the unit via Tools/Settings/Map/Map Info gmapsupp.img: (7x0/7x5) nuvi SD Card drive (supplemental mapset)ĥ. gmapsupp.img: (7x0/7x5) nuvi drive (supplemental mapset)Ĥ. gmapprom1.img: (7x0/7x5) nuvi drive only (secondary mapset) example: North American / European unitsģ. gmapprom.img: (7x0/7x5) nuvi drive only, (primary mapset)Ģ. Here's a list of the nuvi 7x0 & 7x5's mapset names & their relationship with the nuviġ. *Note: Before fiddling with mapsets, make a backup of them first, especially gmapprom.img as this is your main detailed mapset. City Navigator Europe NT 2009 = SD Card drive supplemental mapset (gmapsupp.img) US Topo 2008 = nuvi drive supplemental detailed mapset (gmapsupp.img) City Navigator Mexico NT 2008 = nuvi drive OEM detailed mapset (gmapoem.img) City Navigator North America NT 2009 = nuvi drive main detail mapset (gmapprom.img) The nuvi 7x5 can access up to nine different mapsets (*one* on the SD Card) The nuvi 7x0 can access up to six different mapsets (*one* on the SD Card). These mapsets all reside in the x:/Garmin folder on both the nuvi drive and the SD Card drive. You can have various mapsets loaded on your nuvi.not just the basemap and detail map.
