I had the dealer do the trailer update on my 24 Ranger while it was in getting new tires on March 19th. They plugged the computer into the obd port to update it. My Gateway update came over the air while my Ranger was parked at home on March 25th. The dealer told me the Trailer over the air...
My background update happened yesterday over the air...the trailer update I had the dealer do as I will be towing the travel trailer in April because I didn't want to wait for the over the air update. Everything is working fine so far.
