One more thing I learned about the Matrix Radio in a Vibe .. I was able to get the Toyota Matrix radio to work in my Vibe, and was able to make adjustments to the bezel to look OK (not perfect but good enough for the kids I hang with) and speakers wiring worked out with the adaptor. However, I was NOT able to get the radio to illuminate. I researched the wires for the Matrix radio and none of them seemed to have a wire to mate with the instrument lights (and dimming options) when installed in the Vibe. Maybe all the lights in the Matrix radio were burned out.. but would be very surprised if all of the bulbs had failed.
Just thought I would share this. If someone else here was successful with instilling a Matrix radio that lights up into a Vibe, this news would help me conclude my luck in picking radios from the junk yard, with working lights, is about as good as my picking women.. Not very good..

Thanks
