2002 Buick Rendezvous question

[sincitymedic]

I have a 2002 Buick Rendezvous with the 6-disc in-dash changer. It is serving me well & I actually think the audio sounds pretty good (I have the so-called premium edition).

 

My question is this: does my 2002 Buick have wiring available for the Class II ODB-type radios that were introduced in 2003 on up? I need one of these in order to find access to any auxillary jack(s) for Sirius installation. I am currently using the FM modulator, but think the sound pretty much sucks. If the wiring is available, I can easily find a 2003+ GM radio that has the ODB & has a "Band" button (mine has a "CD/Aux" button).

 

If I don't have the wiring, how hard would it be to buy a new wiring harness & install it? Are there other options for wiring the Sirius into the current HU wiring (soldering to current wires or something)? I just can't believe that there are no options available.

 

Any help or advice would be greatly appreciated. Thanks so much.
