It concerns me that whoever wrote the description of the capabilities of the tool and any associated software can't describe it in understandable terms.

You MAY be able to get a cable that will work with INPA (or ISTA) from Amazon for 35% of that price such as this one, BUT see caution below: I have the BimmerGeeks K+DCAN cable, and it does work with INPA, but it is rather pricey at $45. You can get the software (free download) from various sites, including either BimmerGeeks, or Bimmerfest:

Assuming your laptop has Windows 10 OS, minimum 2GHz processor and 4GB RAM, with at least 60GB free HD space (for INPA & SP-Daten files, E89, a LOT more HD space needed for ISTA), any of the following applies. I believe you need a K+DCAN cable for INPA or ISTA, although I am NOT familiar enough with "Geek-speak" to give you a good definition of what that means.
