HEMA HN7 GPS Map 150 K Upgrade – Restoring the Useful AUS 250K map.
Just a reminder that it is easy to restore the AUS 250 K topo map after the AUS 150 K map upgrade.
The upgrade process removes the 250 K map and installs the 150K map.
But after six months of HN7 use, I find the 250 K map is somewhat easier to read when travelling and touring, as distinct from destination navigation.
For me, the 150 K has some extra detail yes, but the background colours make the map content visually harder to read at a glance on the road.
When you carry out the HEMA 4WD Maps online update, the updater makes a backup of your old system and maps.
Find the backup folder on your PC.
You just copy the three required files for the 250K map back into the “Hema AUS Seamless Maps” folder on your HN7 SD card.
The files are called “Australia Topo 250k 1102”.
There is a MAP file, a Legend file, and an OZF4 file.
Then you will have both 150K and 250K maps.
I have also added the QLD Sunmap 25K topo maps to my HN7, after map conversion from ECW to OZF type.
Make up a separate folder under the “Maps” folder on the SD card and copy your extra map files into it.
If you do the 250K restore to your HN7, you probably should make it also available to the PC based Hema Navigator program, by restoring the 250K map files to the
HN7 Oziexplorer Navigator map folder, or by re-installing the program from your updated SD card.
The HN7 is a truly great GPS unit for offroad use and worth every cent.
No associations with Hema or resellers etc, mike
