I am still wondering why the instructions seem to imply that the vehicle needs to be 'running'? I did the last one with the Expedition in the 'ON' position but engine not running. Is this the way most of you do it....too.?
I do a combo, start the truck and get it started, turn off the motor and back to “On” without opening the door. I sit and play mindless games on my phone, or watch YouTube on my iPad, if cold I might start it back up. If I am driving a good distance and don’t need Nav I will do it then.
Running is better, because unless you have upped the timeout via FORScan, you could have the unit turn off. My timeout is much longer than stock, so no issue there.
