As I understand it, the possession of GPS trackers with a listening function is prohibited in Germany. Meaning that the environment of the tracker can be listened to by a built-in microphone.
Suppose someone owns and uses a GPS tracker with a listening function. And the person opens the tracker, physically removes the microphone - e.g. by cutting off the microphone cables and removing the microphone. Would it then be legal to own and use the tracker without the microphone?
The listening function would still be available in the tracker software, but without the microphone it would be impossible to listen to anything.
