Return the car stereo head unit back to its original location in the dash board, be careful with cables that you just installed so that they do not unplug or get kinked by the head unit.
If you had removed screws to pull the car stereo head unit out please screw those back in.
If you had removed the dash board during installation please return it back to its original location.
Now that your XM Direct system has been installed your XM Universal Tuner will need to be activated. Details on how to operate your head unit in XM mode are listed on the following page. Tune your car stereo head unit to the XM Preview Channel, channell and follow instructions for activation. You can also go on-line at XMradio.com or call the toll free XM activation number at 1-800-967-2346. Once you have activated your tuner box make sure the XM antenna on the outside of your car has an unobstructed view of the sky.
