this item is terrible, and I am returning it first thing tomorrow. it would not display information of my truck, vin, make, model and would not scan my engine or transmission or nothing else for that matter, and it's not my truck because I've used other cheaper and lower quality scanners and they worked just fine. its clear now why the saving was over $200 because it was not worth $50 and who ever the manufacturer is and Walmart should be ashamed for peddling this item to the public. Whoever reads this review, please save your money because it's not worth it. I spent 2 days trying to get it to work, but I'm returning it ASAP.
