With Pass-thru you establish a direct connection between the car and the manufacturer's data server. This gives you access to the car at the deepest level. You make the correct diagnosis faster and receive important technical information that you cannot find anywhere else.

It is almost impossible for a universal car company to arrange a Pass-thru in between the companies. It takes a lot of time, and if it worked once, it doesn't mean it will work every time.

GMTO is always up to date with the latest trends and technology and closely monitors all changes made by the manufacturers.

GMTO guides you through the entire process so that you can do pass-thru in an easy way.
