This adapter will allow you to use your stock GM XM Car Antenna with your SIRIUS Satellite Radio. This is a great adapter for people who are using the GM Connect and want to use their stock XM antenna instead of a SIRIUS Magnetic antenna.
The XM Antenna will not pick up the SIRIUS Signal quite as strong as the SIRIUS Antenna.
NOTE:This adapter will only work with single input antennas. Please check to make sure that your antenna is compatible prior to ordering. We do not compile a list with compatibility for this application.
Not for use on Vehicles that have Internal XM Antennas, like those on the Side Mirrors.
