Hello All
I have this unit : JY-TQ158N4G (last firmware) & default ringtone for mobile incoming call is old & dont like it.
How do I change it / find it & delete it ?
I like to just use other music or sound file but need to know what to call / where to copy to please?
Also Does anyone use offline base maps for navigation ?
I travel into area with no mobile coverage so need to use offline / other base maps for roads & like to use if possible
