It is in your Settings - I am not super familiar with the exact path to it yet (only have had my blazer for two weeks now) it's under the Car Settings under the General Settings.Wait..... what?! How do you do this!?
I wouldn't say they are always free; originally they were a "dealer package" on the car - basically they wanted to charge me $3,995 extra - for tints, wheel locks, all-season floor mats, "pin-striping" (that it didn't need), and some other crap.You got free wheel locks with your Blazer?
