I hear you have to have the steering wheel control option, which the manul alludes to being standard...
The owners manual doesn't include the (if equipped) after the steering wheel controls. I wonder if at the last minute some bean-counting genius at GM thought it would save $$$ if the steering wheel controls became an option.
To say that the DIC is standard is misleading. Nowhere that I have seen, including brochures, manual, and press releases, does it say anything about the DIC losing functionality w/o steering wheel controls.
I have an idea though... Assuming that the wiring in the column is present, and the DIC module is the same (probably are), would it be possible to add this feature simply by changing the steering wheel?
This is something I've seen done with Pontiac Firebirds that optionally had the steering wheel radio controls. Simply changing the steering wheel made for functional wheel controls....
Do any of you all have access to the '03 service manual to see if wiring is present and the DIC module PN is the same? I bet it is, but I don't want to bet the price of a new steering wheel through GMPartsDirect or Dal at VanDevere...
Apart from the above idea, perhaps if we originated a letter writing campaign to GM to make good on their not so standard equipment DIC...
Cheers,
