While I have not tested all the cars/trucks you mentioned I do own a 2001 Dodge Ram 4X4 and have found that MY OBD Link CI connects and functions as it should. It works with the included software and Centerfuse. In Centerfuse I put it as an Elm 327 and get all the reading as well as DTCs (Didn't put my gas cap on tight). I would recommend this to any one and add that mine came with a coupon to upgrade the CI to the OBD Link at a dicounted price if I wasn't happy with it and wanted to get the upgraded one. So I agree with you 99% and love the fact that unlike the cheap e-bay ones you can update/upgrade the Link/CI with new software so this is a future proof purchase.
