I see alot of conflicting info on what Techstream cable I need for my 01 is300 to do active tests, customize settings, etc. People say I need a 2.0.4 firmware version cable to fully access the customize menu. But then 1.4.1 only works with cars before and some post 2006 and 2.0.4 only works with some 06 and up. I have bought a 1.4.1 cable and couldn't access barely anything. I have seen people with the 1.4.1 cable that can fully do advance features.

My question is did anyone have any success in using the cheap 1.4.1 cable?

Access varies a bit in the years.
