I bought one of those kits for my wife's Chrysler from there. I thought I had a problem with it, as it would not remember the presets. I sent it back and they exchanged it out with a new one--same problem. My wife told me that she never had a problem. I disabled driver 1/ driver 2 key memory and problem was solved. It was not recognizing my driver 2 presets. I know, not related to the ST, but they are a good store and take returns no questions asked. I see also that you can buy a "open box" one there for 20 bucks less....
