  • 1) GPS MAPS: Corrupt SD Card

    If your Garmin GPS unit gives an error to say that the "SD Card is corrupt".... There could be various reasons for this, and it does not necessarily mean that there is something wrong with the T4A SD Card. Please try the following solutions: • Reboot your GPS unit to clear the error • If that fails, connect your GPS unit via a USB cable to your PC – copy and paste the contents of the SD Card to your PC; then format the SD Card; then copy and paste the files from your SD card back onto your SD Card. • If that fails, please update your Garmin via Garmin Express which keeps your device up to date from Garmin.
  • 2) GPS MAPS: IMG file installation for the Garmin Overlander

    T4A Garmin Image File Installation for the Garmin Overlander

    10. Tracks4Africa data should now be active and visible when viewing the map
  • 3) GPS MAPS: Routing Problems

    *Please note: all reference here is made using Basecamp. You can try this with Mapsource too – although Mapsource does not transfer the T4A GPS maps version 18.10 and later properly to a GPS unit. We therefore recommend Basecamp for transferring routes to a GPS unit.   Firstly, about transferring routes: we do not advise our clients to do this. The transfer of routes between Garmin's Basecamp and GPS is a dark science which yields different results based on which units are used.  It has nothing to do with the maps loaded.   However if you are going to try and do this then note the following: Sometimes customers report various routing problems:
    • Basecamp is calculates routes incorrectly, or routes and times are wrong
    • Routes and times are incorrect on a GPS unit
      For problem-solving please try this:
    • Basecamp and your Garmin GPS must have the exact same maps loaded, i.e. the map you used for calculating the route in the first place must also be on the GPS
    • Uninstall all versions of T4A from your Garmin and BaseCamp. The old and new versions respectively.
    • Then do a fresh install on BaseCamp of your T4A GPS Maps.
    • Then recalculate the routes on BaseCamp and then send them to your Garmin GPS.
    • The GPS will always recalculate the route once loaded (on some units you have to import the route after transferring it).  For this reason the route calculation settings on the GPS and your Basecamp software must also be exactly the same else you will get different results.  E.g. if you use Shortest Distance on Basecamp then GPS must also be set to Shortest Distance (these settings are not transferred to the GPS)
      • In some cases it simply does not work.
    • If you succeed in transferring a route and you select this route then your GPS will now try to get you to the start of the route. If your starting point is different from what you calculated on the GPS you will have to recalculate the route from your current location.
    If the problem is more that you cannot create a route in Basecamp between 2 point because of possible “breaks” in a track:
    • In Basecamp, under your activity profile, check if any of your "avoidances" are ticked? We do not have Interstate or State Highways in Africa, and if those are ticked, it causes problems when trying to do routing in Basecamp. The best is to untick all of them - go to your activity profile and click on the arrow, right at the bottom  you can "edit activity profile" and the options box (screenshot below) will open up. Select activity profile and then go to routing, to see which avoidances are switched on. Note that if you have one profile for driving, one for motorbike, and one for hiking, you will need to untick it for each activity profile.
    • If you do have avoidances ticked, please untick them and click on OK - now try the same route again, and see if the map still re-routes you on a detour for no reason.
    • Sometimes we have tracks in a concession area, where one may only travel with a guide, e.g. the northern section of the Skeleton Coast in Namibia. So we have the tracks in the map, so you can still do planning for this area if you want, but we put a break in our roads, so you cannot navigate directly into this area. There is usually also a waypoint here that says "permit required" or "no entry north without guide".
    Best practise: We normally advise people to calculate their routes on Basecamp in order to do their trip planning.  Then on the GPS on the day of your travel find the destination and let it calculate the route from where you are to that destination. You may want to print your itinerary or even send some crucial waypoints/POIs from your trip plan to your GPS which is then stored under Favourites for easy access, as waypoints/POIs to route to on your GPS.  
  • 4) GPS MAPS: BASECAMP VER 4.7.0.0 MAPS TRANSFERRED TO GPS ARE NOT SHOWING ON THE GPS (WINDOWS ONLY)

     The problem lies in Basecamp.

    We have advised Garmin of this issue.

    Temporary Solutions:

    If you have an older GPS unit (ie. Mapsource is only compatible with older units) - Click here to download a free version of Mapsource and to use that instead of BaseCamp. Your problem should then be resolved

    OR

    Contact our sales staff for assistance.

    Our sales staff will then send you a temporary download link, containing an .img file which you will have to install on your Garmin unit.

    Please follow these steps once you have received the download link email / download link:

    Please download this file in the email you will receive from Tracks4Africa. You will be directed to a downloads webpage where you will find the .img file to download unless you have been emailed the .img file directly you don't have to access it from a downloads page then.

    It is advisable to access the webpage on the internet, via a Google Chrome or Firefox browser for best results. (ie. do not try to open the downloaded file or run it on your PC - its an .img file for a GPS Unit).

    Then connect your Garmin GPS unit to your PC.

    Then in Windows Explorer, or from a relevant spot in your PC, you need to copy this .img file to either: (Please note different GPS units are behaving differently):

    • an SD Card in your GPS unit directly into a Garmin folder. If that does not work, try to copy the .img file to a Map folder (ie. create this folder on your SD card if there is no such folder yet)
    • or your GPS units' internal memory - to a Garmin folder. If that does not work try to copy the .img file to a Map folder (ie. create this folder on your GPS units internal memory if there is no such folder yet)

    Also, please note:If there are any older Tracks4Africa GPS Map files in your Garmin folder, please copy all these old files to your PC in a safe folder, and then remove them from the Garmin folder on your GPS Unit. Be careful not to remove your Garmaps and their associated license (.lic) files from your GPS units internal memory.

    Your GPS Maps will then be visible on your GPS Unit.

    Troubleshooting:If you loaded the .img file to your GPS units internal memory, and it didn't work, please remove it from there and try loading it to a GARMIN/MAP folder on your SD Card instead, and vice versa following the instructions as per above.

  • 6) GPS MAPS: SD Card Size for T4A Maps & Formatting

    If you purchased our downloadable GPS maps, and want to transfer it to your GPS unit onto an SD Card, you can either purchase an SD Card or overwrite your old T4A GPS Maps sd card if you have one:
    • Recommended size:
      • You could get away with a 2Gb card but maybe 4Gb is safer if you want to load additional files such as our GPS Africa Guide.
     
    • Formatting an SD Card:
      • It must be formatted to FAT or FAT32. Either will work, but the recommended option FAT32.

  • 8) GPS MAPS: Windows XP requires older versions of Basecamp

    Sometimes a customer has an older version of Windows (ie. Windows XP)  and then it doesn't work with the newer version of Garmin Basecamp/Mapsoure - in which case the customer needs to install an older version of Basecamp/Mapsource:
    Customers might sometimes also require a T4A Map with the older installation file of the current version. Please request this to sales@tracks4africa.co.za
