Thread: Deleted GMAPPROM.IMG from Etrex20x... free space not created on device.

I do not understand why user's are always deleting important files or formatting their GPS UNITS.
This forum is full of user's doing this almost every day.
Always put your extra maps on a SD card and not on the units internal memory.

Leave that along.........................

Map Names
These are default map names used by Garmin. Do not use these file names when saving your maps.

gmapprom.img | Primary or Pre Installed Map
gmapprom1.img | Secondary Map
gmapbmap.img | Device Base Map
gmapoem.img | OEM Installed Map (can not be disabled in Map Settings)
gmapsupp.img | Map written to device or uSD card by MapSource
gmaptz.img | Time Zone Map
gmap3d.img | Primary 3D Buildings Map
gmap3d1.img | Secondary 3D Buildings Map


ON THE SD CARD in the folder \garmin\gmapsupp.img (TT50-BRITISH-ISLES+CONTOURS-DEM.IMG)

Been using eTrex units since 2007 and have never run into so many user's doing this delete or formatting their units.
Now have a GPSMAP 66S that uses the same maps I used on my eTrex units.

All maps work when you put the maps in the correct place..........



The best thing any user can do is one of the below items if things are not working the way they should but only as a last thing...........

Do not delete or format your unit.

How do I reset all settings back to factory defaults?

How do I Master Reset my eTrex x0x?
