count the flashes  tell me how many. if it flashes once that means you got 900 miles to go,  7 you got  300 miles to go. it will flash once per 100 miles  then when it flashes 9 the next is solid on. to reset on odometer, trip 1 or trip 2 ours would be trip 2  hold  when its on the car. never let go  turn key off  three sec wait then turn keep  on if you start seeing dashes it s resetting. if not then the next trip one ....
 it wil l reset. let go repeat next time
