I sympathise with your frustration regarding the default ringtone on your JY-TQ158N4G unit. You can generally navigate to your phone's settings and look for Sound or Ringtone options to change it. As for offline base maps for navigation, indeed, many people use them, especially in areas with limited mobile range. You can download offline maps through various navigation apps like Google Maps or saved offline map apps.
