I'm assuming that these are the updated models(x-gauge) Correct??
All Scangauges I sell are the very latest versions available.
Just be aware not all of the Xguage features will work with Toyotas. Most all of the generic codes will work, it's the specific codes like auto trans temp that are not available.
Also, some one asked if the Scangauge would work on a 2004 Taco. Scangauge works on most all vehicles from 1996 a newer.
