Overview: The SIR-GM1 is a
Sirius Satellite Radio tuner that is compatible with select 2003-2008 General
Motors vehicles. The package includes the proper interface cables and a magnetic
Sirius antenna. In addition to the tuner, a subscription to Sirius Satellite
Radio programming is also required.
Compatibility: The SIR-GM1 is
designed to be compatible with select headunits from 2003-2008 GM vehicles that
operate on the Class-2 bus. In many cases, the tuner can replace the factory XM
Satellite tuner. It is also compatible with some systems that support Satellite
Radio operation, but did not come with a tuner from the factory. Compatible
headunit types include CD only, CD + Cassette, and 6-CD changer headunits, as
well as Touch Screen and Non-Touch Screen monitor headunits. The factory radios
in the majority of the compatible vehicles must have a "BAND" button. In some
cases, the radio must have a factory satellite connection (noted by an asterisk
in the chart below). The SIR-GM1 is compatible with most additional factory
audio accessories that might be included, such as Rear Seat Audio Control
Center, Rear Seat Entertainment (DVD/Monitor) System, Heads-up Display, and
Steering Wheel controls.
Compatible Vehicles: The
current list of compatible vehicles includes:
Chevrolet||Chevrolet cont'd||GMC cont'd||Pontiac|
* Radio must have factory satellite
**Slight modification of the Factory SDAR Interface cable is required.
The SIR-GM1 is designed to emulate many of the factory SDAR (Satellite
Digital Audio Radio) commands found in the vehicle, including Channel Tune
(up/down), Fast Tune (up/down), Category Search (up/down), Category Tune
(tune within a category), 12 presets (6 for each band), and Preset Scan
Capability: When the SIR-GM1 is installed it has the capability to show
the following information on the headunit display: Channel Number, Channel
Name, Category Name, Artist Name, and Song Title Name. The number of
characters displayed in the Artist Name or Song Title Name varies by
headunit type (8 or 16 characters). Text Scrolling and/or Paging is not
supported with the SIR-GM1.
