Purchased a scanguage II to enable the reverse beep delete and the seatbelt delete, and did that, and realized I don't need it for anything else. I have the manuals, the unit and the OBD cable. I have the x-guage programmed for those 2 features, so if you are buying for them, it will save you a bit of time. Just set the guages for the 2 custom xgauges and you should be all set. $130 shipped and pp to the lower 48. I dont have a lot of feedback here, but four digit feedback on ebay with the same user name. Thanks!
