Hey guys found the best knockoff(if it actually is)GM Mongoose out there, only $75 bucks but it works better than the vxdiag, which bricked some modules on me but this recovered and reprogrammed them perfectly and works with the newer h***ed 2017 GDS2!!! Enjoy…also I’m new here so some rep points and thanks would be cool
BIG THANKS to e4life
The same functionality; only different from connection:
Vxdiag Nano GM supports wireless(WIFI) and wired connection, while GM Mongoose II Pro works via wired connection only.
