Jeez, good question. I really don't know what to ask for it. I suppose I could find out from the dealer. As far as the buttons go, this is just the module that goes in the back near where the spare tire is. And to be honest w/you, I'm not sure what years it's compatible with. It's from an April 2004 build. And as far as what it's worth, how about 50% of say, what you could get it from Crevier for?. I don't know how much they are separately as I believe it came w/the premium package. Do you have the SOS/wrench button in your overhead console? If you're truly interested I'll be happy to do a bit more digging for you... If Jeff's seeing this, I'm sure he could provide a bit more insight for us.
