Ranger Mods

New user 2015 ranger px

Have a 2019 for ranger lariat. The dealership just upgraded the sync to 3.4. I didn't realize the climate control button was gone. I have read how to fix with forscan. But I have no clue how to use forscan etc. I would take back to dealership but they are awful. When they did the update it wiped out the navigation, which I. Had to pay to fix. I understand I need to buy a obd2 adapter and download the forscan software. Would someone tell me step by step what to do after I get that? .im not understanding how I make sure I save my configuration. Nor what numbers to apply to forscan.....tks
