Enable aux input

Do I have to connect my Tech2 to a pc and use Tech2Win in order to add the u42 option for the aux input? If not, can anyone guide me through the process?

your tech2 and tech2win are the same thing
did you change the radio or something? if your aux is not working then it's broken, sometimes dirt or something could be in the port try cleaning it with a toothpick or something of that nature.

The NAV did not originally have the aux enabled. I would like to enable it and run the harness to add aux input into the radio.
