I have heard a lot of reference to the GT1 scanner for the X5. I know that this is a factory scanning tool. I currently use a Snap-on MT2500 scanner to scan my vehicles and it gives me a lot of codes and data that an OBD II won't. I have been interested in what the GT1 does other than data and codes and if it is a better tool than my MT2500 for scanning and diagnosing faults. If it is, is there a post that gives a step-by-step process to obtain one/best place to buy and how much? Any informaiton would be great.
