How to tell if Superchips is unlocked
I'm looking at a Superchips 3865 on ebay. The seller is unfamiliar with it as he is selling it from his father's truck whom is now deceased. He doesn't know how to navigate the menu to show it is unlocked. I could probably figure it out if I had it in my hands, but it's eBay. Could someone give instructions on how to check it?
