This version works on Tomtom v8.x or v9.x, with a complementary program you can download here.
This version fixes bugs in v2.2 version : crash when trying to choose an itinerary although there is no itinerary available.
If you are using Tomtom v8.x or v9.x navcore, you must install Offroad Navigator v3.0 and another program to solve screen flickering problem with plugins .
Known problems : this version doesn't work on One V3 where it can't even be launched.
Offroad Navigator can not be installed with Tomtom Home because it is not known as a Tomtom software.
Proceed as follows to install it :
With Offroad Navigator, you can navigate without maps, just following a course and distance to the next point. GPS datas are taken from an itinerary file, created with the Tomtom navigation application or any other software able to create an ITN file.
You may also navigate to a point, just by giving its GPS coordinates. The coordinates must be given in decimal degrees, with negative values for longitude west of Greenwich and negative values for latitude in the south hemisphere.
You may also choose a favorite to navigate to.
The waypoints can be off from any road, Offroad Navigator providing a solution to navigate on any place, even if you don't have the corresponding map.
Offroad Navigator has got several screens :
In the navigation screen, Offroad Navigator displays :
At any moment, you can choose to ignore one point and navigate to the next point in the itinerary, by using the "Next >>" button. You can also choose to go back to the previous point with the "<< Prev " button.
If you approach from the current point within a distance lower than the Target Distance defined in Setup screen, Offroad Navigator will automatically consider it as visited and calculate the new course and distance to the next non-visited point.

By default, Offroad Navigator hasn't got any map visible. Anyhow, you can add maps that you need to create and install yourself.
Here are some tricks to setup maps :
<upper left corner longitude> <upper left corner latitude> <lower right corner longitude> <lower right corner latitude> <file name>
<upper left corner longitude> : longitude in decimal degrees (with a "." before decimals) of the upper left corner of the map
<upper left corner latitude> : latitude in decimal degrees (with a "." before decimals) of the upper left corner of the map
<lower right corner longitude> : longitude in decimal degrees (with a "." before decimals) of the lower right corner of the map
<lower right corner latitude> : latitude in decimal degrees (with a "." before decimals) of the lower right corner of the map
<file name > : file name of the BMP file containing the map with the complete path /mnt/sdcard/offroad/maps/
config.map file example
-1.6 48.4 -1.5 48.1 /mnt/sdcard/offroad/maps/carte-0-0.bmp -1.5 48.4 -1.3 48.1 /mnt/sdcard/offroad/maps/carte-1-0.bmp -1.3 48.4 -1.1 48.1 /mnt/sdcard/offroad/maps/carte-2-0.bmp -1.6 48.1 -1.5 47.8 /mnt/sdcard/offroad/maps/carte-0-1.bmp -1.5 48.1 -1.3 47.8 /mnt/sdcard/offroad/maps/carte-1-1.bmp -1.3 48.1 -1.1 47.8 /mnt/sdcard/offroad/maps/carte-2-1.bmp
In this screen, you can setup the following parameters :
In this screen, you can choose the colors of the differents objects and areas on the screen.
In this screen, you can choose the customized background that will be used when no map is available. These files are Bitmap files (with 8 bits or 24 bits color depth), with size equal to 480 * 272 pixels for wide screen Tomtom and 320 * 240 pixels for small screen Tomtom. If one of these 2 parameters is empty, then the corresponding screen is displayed without background.
You can also decide, using the "Map" parameter, if you want to use maps or not.
If you've got the standard menu (eg. if you have no tomtom.mnu file on your disk), then one icon is added at the end of the main menu, as for any software with a .cap file in the /sdkregistry directory.
If you've got a tomtom.mnu file, you need to modify it to see the corresponding icon
in your personalized menu. Add a line :
MENUITEM|TASK_SDKn|with "n" equal to the right number (between 1 and 9) for the corresponding /sdkregistry entry, depending of the number and order of .cap files in your /sdkregistry directory.
This version fixes bugs in v2.0 version and includes some enhancements :
This version is the first version which works on any Tomtom versions, without Tomtom SDK.
It has got all the functionalities of the previous versions except the navigation to a Favorite POI. Anyhow, if you want to navigate to a Favorite POI, you just need to create an itinerary with this POI as a single waypoint and then navigate using this itinerary file. The non-snapped coordinates mode doesn't exist any more as it is not supported by recent Tomtom versions.
This version fixes the problem on GOx20, where Offroad doesn't start. It is due to the snapping disactivation functionality, which is not supported by the SIRF module of these devices. This functionality is disactivated on such devices.
This version allows a negative geoïd correction and it fixes a bug with geoïd correction, when it is not zeroed in the NMEA frames, although the altitude is already fixed.
This version provides the following enhancements :
This version allows you to really use Offroad with Real coordinates, using non static navigation mode. In such mode, the coordinates are refreshed whatever the current moving speed is.
Important : this non static navigation mode may produce a very unstable map display in the Tomtom application, it's normal. When Offroad Navigator is used in Snapped coordinates mode, eg. static navigation mode, the map display in the Tomtom application remains stable. When Offroad Navigator is stopped, even it has been used in Real coordinates mode, the static navigation mode is restored and the map display in Tomtom application must become stable.
