TomTom maps and Map Region Codes

Each Bridge device is delivered with a TomTom map. Bridge has different types of maps for different regions, the combination of which is brought down to a single number: the Map Region Code. This Map Region Code will be enforced by the device, meaning that you can only use maps that have the same Map Region Code.

If you look at our releases you'll see the regions that are available. Note that the "Europe" and "USA, Canada and Mexico" maps have the same Map Region Code: 1. This means that you can install a "Europe" map onto a device that currently has a "USA, Canada and Mexico" map on it, and vice versa. And even though the "Europe" and "Europe Truck" maps are for the same geographical region, they have different Map Region Codes because truck maps are different from regular maps. This means that a device with a "Europe" map on it, will not accept a "Europe Truck" map. The installation might succeed but you will be greeted by a "No maps found" message when trying to use the device.

The {dcp-id} variable mentioned at the "Software update" application documentation, ends with the same value, eg. XX1234X00002.

IMPORTANT: In the 17.4 Baggio release TTC maps will be deprecated and no more map updates will be released with this map format. To change to the new NDS format map a build update is necessary. Information on how to get an NDS build will follow as soon as they are available.

Navigation Data Standard maps

As of the 17.4 Baggio release Bridge has switched to support the Navigation Data Standard (NDS) map format that offers more content. As of 17.4 Baggio no new map updates will be released in the old TomTom Classic map format.

This additional content will allow better map configuration and more routing features in the future. With this new standard the old Map Region Code has been disabled so that any map will work on any Bridge device regardless of the region. With NDS maps you will also be able to specify which map areas or map data you would like to install as well as allow your users to receive map updates over the Internet. In most cases this means a faster install that requires less data.

Installing map areas

The main use case will be installing only the map areas that are applicable to your user. For example, if your users only drive in the UK then you can install only the UK area rather than the whole of Europe. To demonstrate this we'll use an example where only the UK is installed:

  1. Download the region you would like to use. You can download the region here.
  2. Extract to micro SD card using 7-Zip (do not use windows explorer and use a fast 32GB SD card).
  3. Remove unneeded regions from the package-list.map file.
    • When removing regions, remove the whole line, do not remove only the "parent" or "group" attributes or you will have installation problems. Always leave europe-empty and european-oceans packages as they are always required.
    • Example, installing the UK map area and the 3D building data:
      {
          "schema": "1",
          "packages": [
              { "name": "europe-empty", "path": "map/europe-empty_9127.2015.12_all.ttpkg", "version": "9127.2015.12", "group": "map" },
              { "name": "europe-region-147-united-kingdom", "path": "map/europe-region-147-united-kingdom_9127.2015.12_all.ttpkg", "version": "9127.2015.12","parent": "europe-empty", "group": "NDS" },
              { "name": "europe-region-147-united-kingdom-3d", "path": "map/europe-region-147-united-kingdom-3d_9127.2015.12_all.ttpkg", "version": "9127.2015.12","parent": "europe-empty", "group": "NDS" },
              { "name": "europe-region-900-european-oceans", "path": "map/europe-region-900-european-oceans_9127.2015.12_all.ttpkg", "version": "9127.2015.12","parent": "europe-empty", "group": "NDS" }
              ]
      }
      		
  4. Insert the SD card into the device and run SW update. Only the desired regions will be installed.

 

Weekly map updates

By default users will be allowed to update their map over WiFi. You can also disable this, or allow over any network type if data usage is not a problem for you.

Adding custom POIs

Custom POIs can be added by placing their ov2 file onto the device. The ov2 files need to be added to /sdcard/locations. To add an icon for the category, you must create a directory called ov2_icons under locations, so /sdcard/locations/ov2_icons. There you create 4 directories for the different dpi levels: ldpi, mdpi, hdpi and xhdpi.

The easiest way to do this is to create a zip file that contains the files in the right directory structure, and add it as a package to your configuration.

The icons need to adhere to our specifications in order to blend in with the Navigation application. You can find some sample icons here.
