OK... Got warm enough to finish this thing.. I did take the dash etc apart more than needed, but I wanted to make sure I could see everything possible. If you do this install you will only need to swing the glove box door open. This is accomplished by depressing the stop on the righ side of the glove box and allow it to fall down.
Steps taken to complete install.
<LI>Follow instructions for removing center console found
here
<LI>Remove two allen head bolts near the top of the center stack facia. This will allow you to give the center stack facia a good tug and expose the radio mounting bolts etc.
<LI>Remove the radio and install the wire harness provided with the Terk XMDGMK kit.
<LI>Route the extra piece on the new harness around the rear of the radio cavity under the right vent tube. Then pull this harness down by reaching up inside the left opening of the glove box cavity.
<LI>Re-install the radio by re-connecting the wire harness to the rear of the stereo and gently pushing the stereo back into position checking to ensure no wires are being pinched. Bolt radio into place.
<LI>Using double sided tape, install the XM universal tuner box up inside the glove box cavity on the plastic frame next to the right side of the radio. Make sure all the connection points are accessable for later attachment of antenna etc.
<LI>Install antenna in a location best suited for your vehicle/radio. I used a piece of sheet metal glued to the underside of the top center of the center stack so the antenna could stick magnetically to the sheet metal through the plastic, and sit in the window instead of outside.
<LI>Route antenna wire back to the XM Universal tuner box and ensure proper connection.
<LI>Install the left and right (red and white) RCA cables into the XM universal tuner box.
<LI>Install the data control cable into the XM Universal tuner box.. allow the wires to hang down out of the glove box opening.
<LI>Using double sided tape install the GM interface box onto the XM universal tuner box. Make sure the RCA and Data connections are pointing down, and that the wire harness from the stereo is plugged into the interface box prior to sticking the interface box to the universal tuner.
<LI>Plug the RCA and Data cables into the GM interface box.
<LI>Tie all excess cable together below the universal tuner box and GM interface to make a clean install and avoid any rattles etc down the road.
<LI>Re-install the center stack facia
<LI>Re-install the center console
Now it is time to call XM and have them enable your radio. The control of the XM is now done through the radio and the steering wheel controls..
