I have the OBD MX Bluetooth. My son bought it for me as a gift. About the same price as the one silicon 212 mentions and does the same if not more. It's paired to the "OBDLink" app down loaded free on my android phone. I have several other scanners that I use in the shop so it stays in the car and only gets used on long trips or if the car hiccups. But pretty impressive for size and cost. I've even used it to diagnose other peoples cars when not at the shop.
