    nüvi 7x0/7x5

    The Nuvi uses a disk based file system and can support multiple maps on the hard drive and the SD card.

    You can have various mapsets loaded on your nuvi...not just the basemap and detail map. These mapsets all reside in the x:/Garmin folder on both the nuvi drive and the SD Card drive. The nuvi 7x0 can access up to six different mapsets (*one* on the SD Card). The nuvi 7x5 can access up to nine different mapsets (*one* on the SD Card)

    Example:

    Mapset 1. City Navigator North America NT 2009 = nuvi drive main detail mapset (gmapprom.img)
    Mapset 2. City Navigator Mexico NT 2008 = nuvi drive OEM detailed mapset (gmapoem.img)
    Mapset 3. US Topo 2008 = nuvi drive supplemental detailed mapset (gmapsupp.img)
    Mapset 4. City Navigator Europe NT 2009 = SD Card drive supplemental mapset (gmapsupp.img)
    Mapset 5. nuvi drive Basemap (gmapbmap.img)

    *Note: Before fiddling with mapsets, make a backup of them first, especially gmapprom.img as this is your main detailed mapset.

    Here's a list of the nuvi 7x0 & 7x5's mapset names & their relationship with the nuvi
    drive/SD Card:

    Nuvi map naming convention
    ------------------------------------
    1. gmapprom.img: (7x0/7x5) nuvi drive only, (primary mapset)

    2. gmapprom1.img: (7x0/7x5) nuvi drive only (secondary mapset) example: North American / European units

    3. gmapsupp.img: (7x0/7x5) nuvi drive (supplemental mapset)

    4. gmapsupp.img: (7x0/7x5) nuvi SD Card drive (supplemental mapset)

    5. gmapoem.img: (7x0/7x5) nuvi drive only (OEM mapset), user accessible, cannot be unselected from the unit via Tools/Settings/Map/Map Info

    *Note, when using the following default system maps as user maps, you'll naturally lose their default map attributes.

    6. 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/Basemap

    7. gmaptz.img: (7x5 only) nuvi drive only (default 7x5 Timezone map), configurable as a supplemental map; rename desired mapset to gmaptz.img

    8. gmap3d.img: (7x5 only) nuvi drive only (default 7x5 3D Buildings map), configurable as a supplemental map; rename desired mapset to gmap3d.img

    +9. gmap3d1.img (7x5 only) nuvi drive only (secondary 7x5 3D Buildings map), configurable as a supplemental map; rename desired mapset to gmap3d1.img


    Nuvi internal (diagnostic utility) OS map naming
    -----------------------------------------------------------
    7x0/7x5

    1. PROM1 = gmapprom.img
    2. PROM2 = gmapprom1.img
    3. Suppmap1 = gmapsupp.img (nuvi drive only)
    4. Suppmap = gmapsupp.img (SD Card drive only)
    5. Dir DB = gmapoem.img
    6. Basemap = gmapbmap.img

    7x5 only

    7. TZMap = gmaptz.img
    8. 3DMap 1 = gmap3d.img
    +9. 3DMap 2 = gmap3d1.img

    re: nüvi 7x0/7x5

    Correction/Addendum for 8 & +9 (both of them):

    Can be on the nuvi drive or on the SD card (but not both).

    Example: You want to add 3D Buildings maps and/or supplemental maps to your nuvi 7x5 device but don't have enough free memory without removing any of the existing map img files. If your not using either or both of the 3D Buildings map names on the nuvi 7x5 drive, you can instead use those map names on the SD card. You can then have 3 img map files always available on an SD card (gmapsupp.img, gmap3d.img & gmap3d1.img).

    Another Addendum/Caution:
    When using both the gmap3d.img & gmap3d1.img filenames (at the same time... whether they are together on the nuvi drive, on the SD card or one of them on each), if one or both of the filenames is/are used for a supplemental map/maps, they will be grouped together in the "Map Info" list of the nuvi 7x5. Therefore, just like when the filenames are used as normal (for 3D img files on the nuvi drive) they can only be enabled or disabled together in the "Map Info" list of the nuvi 7x5. If both 3D map img filenames are used for supplemental maps and they both cover overlapping areas, this can potentially cause a problem. One of them will overwrite the other and you will not have the ability to turn only one of them off.

    gmapsup2.img on SD card should also work on 7x5.
