There are different versions of OziExplorer, one for the PC, one for Android & one for WinCE, the WinCE version will run on your device.
As I mentioned and others mentioned & explained on the FixMyGPS forum, I do not believe your device will run all those maps that the device/seller claims can be run on it.
Maps are only as good as the information entered into them by the map developers, if the maps you are using don't have the relevant information that's accurate then most likely none of us can help with your issue.
With iGO being so far out it could be one of the route settings in the program or the map not accurate that's causing it.
Perhaps you should talk to the seller of the GPS unit?
Get them to explain just how to run the Garmin maps (or others) on your device.
I think the information they are giving out about that device using all those maps is false, so I'd be trying to get them to explain and instruct you on how to use the other maps they claim can be used.
