If all you want to do is adjust settings I think it's a great deal, way cheaper and easier than Techstream.

I modified:

-ECO bar off
-Seat belt buzzers off
-Headlight "coming home" time to 0
-No more auto relock if you hit the unlock button on remote but don't open the doors immediately
- Windows down from remote
- Disabled auto door lock linked to transmission gear
- Silenced remote lock/ unlock beep
- Windows up/ down from driver's key slot
- Rear wiper set to 5 seconds with tear wipe cancel
- Disabled panic alarm



I see no reason why it wouldn't and Carista's website shows it will work. Worked on a 17 SR5 and a 19 ORP, other than the addition of TSS there's no difference from your 20.
