I tried upgrading the HERE maps on the navigation system in my LandRover Discovery Sport P300e using a USB-stick as per the directions given by HERE and LandRover, but after 3 attempts that failed for no clear reason, when I retried yet another time, the update crashed while it was about halfway and now… there is no map left in the system to use for the navigation… nothing… the navigation is completely blind…
What can I do to solve this ?
There are several reasons why this problem might have occurred. Your LandRover will probably show a warning message advising you to go to a LandRover garage and get this fixed, but you can also give it a try yourself first, just make sure you include all of these additional instructions in your next attempt :
- start off by using a USB-stick with no previous navigation files on it – if you do not have a brand new USB-stick of 32GB at hand, you can also try using the current one : no need to format it, just open it in the Finder (on macOS), then inside the folder named “HereV1”, select all files (press the CMD-A key combo) drag them to the Bin and empty the Bin
- goto the landrover.here.com website, login using your account name and pasword, goto “Maps & Services”, click the “Get Latest Update” button of the map you want to install and in the next page that opens, start by downloading and installing the latest version of the MapDownloader-app before you proceed to downloading the desired map itself ; just finish making the USB-installer as usual
- now, before you enter your P300e hybrid LandRover to start the update, make sure to unplug the electrical charger cable before you start your car (so the engine will stay running during the entire update process that may take up to 30 or even 45 minutes to complete – if your electrical charger would be plugged in, your engine won’t start and your car will definitely go into sleep mode before the navigation update is finished ; if you like you can take a drive during the map update, just remember you are not able to see any maps on your screen during the update – you might be able to use navigation though Apple CarPlay in the mean time – and you have to keep the engine running until the update is complete, so you cannot leave the car until done)
- when starting the navigation update in your car, wait with plugging in the USB-installer until the car’s system asks you to do so and make sure you use a different USB-port than you did before
…then proceed as per the onscreen instructions and sit back and relax
…if you do so, the update process may appear to be a little slow, but it will succeed in about 30 minutes. (and if it doesn’t just try again – and if it still fails after a few attempts, the problem is not ‘just an upgrade’ so you will still have to contact a LandRover garage to get it fixed)
That’s it !
