There's a fair chance you can run OziexplorerCE on it, but you'd probably have to do a bit of fiddling to get it installed.

You can almost certainly run Ozi CE on it. And this is really what all the fuss about cheap chinese GPS is all about. Run Ozi Ce on a 4.3" unit and you've got yourself a very cheap Hema navigator.

You need to work out how the GPS program on the SD card is 'addressed' when you hit the 'navigation button'.

Some use a 'shell.ini' file, which you can open and modify with Wordpad or any text editor.

Have a poke around and report back.

Enviro8 is good at this stuff. :)

Just to clarify the additional costs.

$130 - Oziexplorer (you need this to generate map files for OziCe maps)

$40 - OziCE to run on your GPS

0$ - Img2ozf (http://www.oziexplorer3.com/img2ozf/img2ozf.html) (from Oziexplorer) to convert .ecw to .ozfx3 images

$99 - Natmap 250k (All Aus)

Total investment = $269

Then you could add Hema maps if you so desired for a full Hema navigator

One other limitation.

If you go the 'no name' GPS route, (or any GPS for that matter), make sure it has a WinCE 5.0 OS or higher.


Because Win Ce 5.0 and up supports SDHC CD cards. Win CE 4.2 doesn't. So the SD card limit for Win CE 4.2 PNA/PDA is 2Gb.

So what?

Well. :)

If you wish to run Ozi CE with the full Natmap 250k mosaic plus a few other maps, you'll be looking at a 4Gb SDHC SD card. The Natmap 250k mosaic won't compress to less than 2Gb.

You can still run the Natmap 250k but you'll need to load a couple of the smaller map mosaics (north south slices of Australia). Maybe a few 2Gb cards if your going on a really really long and determined treck. Not quite a Hema.

Many cheap GPS are still Win CE 4.2.

It makes the Aldi Tevion look good :)
