The safest way is with a scan tool, on this model you can disconnect a battery terminal and turn on the headlights and wait about a minute, then turn off the headlights and reconnect the cable, this will put it back to factory so all of the presets that have been stored will be wiped, so you will have to start over, it might run somewhat different until it learns the vehicle and how you drive.
