Mobile device cannot recognize DSR1

My PerfectTune app will not find the DSR1. How can I fix this?

This issue is commonly found on Android Phones and Android Tablets. If the Rockford Fosgate PerfectTune app cannot find the DSR1, please check to make sure the "Location" settings on the Android device are tuned "ON". Depending on the device you can access the "Location" option in "Personal Settings" or "Google" option in settings.
