The Teufel Remote App requires the activation of the location services in the iPhone in order to detect local WLAN networks to which RADIO 3SIXTY/MUSICSTATION should be connected.
This is a new security requirement on the part of Apple. The purpose of enabling location services is to prevent their location from being transmitted unnoticed. Teufel does not store any data from the location services.
