Frequently asked questions

Will the CTSx-HAR work in vehicles with Navigation?
YES; Except SRX with Navigation radios.
How can I check if vehicle has XM module?
Turn Radio “ON”, press “BAND” button repeatedly to cycle through AM/FM/XM1/XM2. If only AM/FM is displayed, vehicle does not have XM Tuner Module.
Can I install this harness without removing stereo?
NO; The CTSx-HAR connects to the radio and because of that the radio must be removed.
XM/iPod adapter etc. sounds only on one side. What is the fix?
Late 2004 and early 2005-07 production CTS has the left audio and ground wires switched (compared to 2003- early 04). To fix, switch pins 3 (Blue/white) with pin 4 (Yellow) or vice versa.
