Frequent ask questions & troubleshooting
1. Don’t all STS radios have built-in XM tuners?
NO! Unlike AM/FM tuners, the XM tuner is not bult-into the radio.
XM tuner module is a metal box (See Fig. 20) installed in remote location
(trunk, hatch, below glovebox etc.) and connects to the AM/FM radio via a
16-pin harness. For the A2DIY-STS to work, vehicle must have below
pictured XM Tuner module. See question #5.
Fig. 20
2. Will the A2DIY-STS work in vehicles with Navigation?
YES; works in both Navigation and non-navigation radios with XM Tuner
Module seen in Fig. 20
3. My XM subscription has long expired, will the A2DIY-STS still work?
YES; as long as XM Tuner module remain in vehicle.
4. My XM subscription is active. Will it be lost after installing the A2DIY-
STS?
NO, The A2DIY-STS does not interfere with XM subscription. If subscribed
select “Subscribed”. If not subscribed; an AUX input jack is provided.
NOTE: If not currently subscribed but plan to renew at a future date,
select “Subscribed”otherwise XM will not play upon renewal.

How can I verify vehicle 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, vehicle is NOT
compatible. Navigation radios: if XM softkey is “grayed out”, vehicle
does not have XM tuner and not compatible with the A2DIY-STS.
6. My STS has factory Bluetooth hands-free calling but not able to
stream. Is there something you offer to add music streaming?
YES; purchase our A2D-STS to add music streaming to factory system.
It will not interfere with factory hands-free calling kit.
7. Can I use steering wheel or radio buttons to control music playback?
NO; you must use included media button or Smartphone built-in controls
and display for access/controls.
8. Do I have to pair smartphone to module in order to listen to XM or
AUX?
NO, XM or AUX playback is possible without paring phone, which means
users simply place radio in XM mode (press BAND button) and XM or AUX
device will play. To stream music or initiate/receive Bluetooth calls,
smartphone must be paired to module and radio must be in XM mode.
