I have a 2017 Volkswagen Tiguan. On connecting to the navigation the following message comes up on the instrument cluster: "Please insert a data medium with valid navigation data". What does this mean and how can I fix it?
Your car’s sat-nav should be taking its data from an SD card that’s inserted in a slot inside the glove-box. So, the first thing to check is that the SD card is seated in the slot correctly. But there have been cases where the VW’s software seems to have a light-headed moment and loses the plot (it happens on plenty of other brands, too). One thing you can try is to press the on-off button for the infotainment screen and hold it down for at least 15 seconds. Sometimes, that will actually reboot the system and everything will come to life again, including the sat-nav.
Failing that, it’s a trip to the dealership to have the experts fix it. It may turn out that your data card or the software in the car needs an upgrade, which the dealership should be able to sort out for you.
