Tech2 problem Region code and Onstar ?
 

Hello,

I need some help. I have a 2009 ZR1. The car is a US model. I need to change the Region Code of the car and I would like to deactivate Onstar.

I have found someone with a Tech2 and I have also a card with the GM NAO version 33.004 ... So we tried to change these settings but even after an hour of research I can’t find to correct menu tree where I can change this settings or we did something wrong.
I found them in a menu from the Navigation system but I’m not able to change them there. I can select one with a star but not more ...

Did anyone know where to find the exact menu point to change this settings and or how to do it exactly ?

This would be very helpful.

Greetings,

Pascal

It sounds like you were in the correct menu screen. Like you mentioned only one can have a star. You have to deselect the line with the start before you can apply it to a different one. I don't have my Tech 2 in front of me, but I believe it tells you how to unselect on the screen.
