I am about to order a steering wheel interface off eBay and I need to know which one to get. I've seen people on here talk about the SWI-X but there's another one called the SWI-JACK that they say is better (something about it not being affected by sunlight? but i don't see how since it's inside the dash). The SWI-JACK is only like 5 or 10 bucks more, but will it work? It says it is compatible with all Chevies with the 24-pin connector, which I believe the MC has? So should I get the SWI-JACK or do I have to get the SWI-X?

 

b 4 you order let me check i can tell you for sure i have to get to the papaer work.
Will let ya know asap.
the one i have has the onstar option on it and is workign fine with out the onstar attached to it also.
