PXDX-CTS
QUICK START AUXILIARY INPUT INSTALALTION GUIDE FOR CADILLACE CTS/SRX* WITHOUT XM TUNER
created June 10, 2018
Revised: August 29, 2020

Introduction:
If your 1st-generation CTS or SRX audio system did not include U2K package (XM
Tuner), chances are you have not been able to find a viable solution for
connecting and playing portable audio devices in your car. The PXDX-CTS
Auxiliary input adapter kit allows these proud owners to connect and play all
kinds of audio devices including Smartphones, iPad, MP3 players, iPods etc.
This Kit is exclusive to vehicles without XM tuner;
however, factory radio must be XM ready otherwise
dealer must activate (turn-on) this feature using a
special tool and only then will the radio recognize this
module. Programming (activating) XM is carried out by
GM dealer who may or may not charge a fee for the
service.Please call dealer in advance for details.
See Frequently Asked question at the end of this guide for details.

Frequent asked questions
1. Will the PXDX-CTS work in vehicles with Navigation?
YES; Works on CTS Navigation but not for SRX Navigation Radios
2. I don’t know if radio is XM Ready. How can I find out?
For this you are required to visit dealership who can check and/or activate
this option for you. Once activated (if not already), the radio will recognize
this module. Dealer may charge a fee for activating XM and because of that
we recommend contacting dealer for pricing details prior to purchasing
this part.
3. In 2005 Cadillac moved the TAN/WHITE wire on gray connector, but
we have found some late 2004 models were also affected. If you own a
2004-05 CTS (not applicable to SRX), check wiring on Radio’s Gray
prior to ordering. Doing so guarantees proper playback and avoids
costly returns. Here is how:
if pin 4is TAN/White (See Fig. 12) select 2003-04 when ordering
if pin 3in TAN/White (See Fig. 13) select 2005-07 when ordering
Fig. 12
Fig. 8
Failure to check gray plug (2004-05 CTS) could result in audio
playback on right channel only
5. Can I install this module without removing the radio?
NO; this module fits only the plugs on the radio. .
6. Will I be able to make and receive phone calls with the PXDX-CTS?
NO; however, speakerphone feature does work by which users speak
into smartphone mic and caller is heard on car speakers.
7. Why is this module not compatible with SRX Navigation radios?
SRX Navigation radio plugs are different and because of that our PXDX-
CTS is not compatible. SRX without Navigation is compatible.
