Hello Ruan
So... i am sorry. I can close this help request now. perhaps it was my error.
The last attempt did work. i don't know exactly what i've done differently. i know that when it prompt to turn off ignition and wait, i did it but not troo much
also, there is a window, that will ask you to enable or disable something, i don't remembrer exactly what... i changed that, then make my coding et voila. all is good.
Sorry not to have updated that post.
Still love my gs911
