I just received a bluestar 2010 unit. My issue is that I can't locate the Onstar module to do the installation. I have a 2008 Saturn Astra. Anyone found it out there yet?

I show two possible locations.
1 Behind the driver knee bolster
2. Behind the glovebox.

Let us know if you can't find it.

i have a 2008 astra 4 door with a moonroof

my was behind the driverside knee bolster

to the left of the steering wheel you have a set of light controls, turn the largest knob to the left position, push it in and turn it up toward 12 oclock, the whole control panel should 'pop' off a bit, then pull it out, unplug the connection and set the panel aside

4 torque screws total need to be removed from the knee bolster, 2 under the light control module you removed,
put the steering wheel in the top position and pulled out to give better access to the last 2 screws. 2 on the top right side of the knee bolster
give it a tug, there is a tension clip on the right side
it will flip down, then unclip from the bottom bar - set aside

you can now see the onstar module (it will have 2 antenna connections 2 white connections, one black connection ) - uplug the two white connections - plug them into your costar module, tuck it up inside
