One thing that I have found is that if any button other than on/off is pressed anytime after auto level is completed it will disable that feature. So keep that in mind. Other than that, it is a very awesome feature.
I have a Venom with the same system. For the hitch memory to work, unhitch from the truck, press auto level and let it do its thing, then do not touch the pad anymore only to shut off until you are ready to hitch back up then turn pad on and press...
