Introduction
Many 2005-11 Cadillac STS owners with tons of music and application on
Smartphone will be pleased to find this module. The A2D-STS Bluetooth music
streaming receiver uses the radio’s XM port to stream music applications from
A2DP enabled devices (e.g., Smartphone, Tablet, Kindle etc.) Simply connect the
A2D-STS to radio, pair audio device and stream all applications (e.g., music, GPS,
audio books etc.) on the 6-CD changer or 6-DVD navigation radio. For the A2D-STS
to work, vehicle must have an XM tuner module (with or without subscription).
If subscribed, select “Subscribed”, if expired, select “Not subscribed”; however,
if not subscribed but plan to renew at a later date; select “subscribed”
otherwise XM will not play upon activation.
*Not subscribed means vehicle has XM tuner but no SiriusXM service.

Frequently ask questions & troubleshooting
1. Does the A2D-STS work in vehicles with Navigation?
YES; works with both Navigation and non -navigation radios with XM Tuner
2. My XM subscription has expired, will the A2D-STS still work?
YES; as long as the XM Tuner (Module) is present the A2D-STS will work.
3. I currently subscribe to XM. Will it still work with the A2D-STS?
YES; simply select “Subscribed” from order option drop-down menu.
4. How can I verify my 2005-11 STS has required XM tuner module?
Turn radio “ON”, press “BAND” button repeatedly to cycle through
AM/FM/CD/XM. If only AM/FM/CD is displayed, your vehicle does NOT
have XM tuner module and therefore incompatible.
5. Can I install this module without removing the radio?
NO; radio removal required to gain access to the connectors.
6. Can I use steering wheel or radio buttons to control music playback?
NO; you must use audio device built-in control and display to access/control
music selection or purchase optional Bluetooth remote control.
7. Will I be able to place phone calls over Bluetooth?
NO, this module supports Bluetooth streaming (A2DP) but does not support
hands-free calls. Purchase our A2DIY-STS instead.
8. My module connects and pairs, but playback is distorted, low and
intermittent. What can be done to remedy this?
This is possible in vehicles with Bose amplifiers where the radio does not
provide enough current to power amp and module. I these situations you must
use the accessory wire extension included in kit as per warming on page 3.
