Ok guys, I need someone's help that maybe works at the factory or a dealership. I just ordered my 2008 GMC Sierra 2500 HD, well, it will be a while till I get it, so I was in my officee just going through the brochure, reading about all my new goodies coming my way and noticed a discrepancy. When I filled out the order form in the audio section, it was an extra $300 or so for the in dash 6 disc changer on the radio. I hardly listen to CD's so I jsut took the single CD because it didn't cost any extra. However, looking through the brochure, I notice that on the SLT trim that I picked, the 6 disc in dash is standard with that trim package? Called my dealer and asked if he could check on it. I don't want to pay the extra $300 for it, but if it's already built into the price of the SLT, I'd like to have it since I'm paying for it. He calls me back the next day and says that there's an SLT1 and SLT2 package and the 6 disc in dash is only standard on the SLT2 package, and that I had ordered the SLT1?? NOw I'm no factory GM rep, but I've never heard of an SLT1 or SLT2. I know they offer and SLE1 and SLE2 trim level. Anyone know if this guy is just being a typical salesman or is there any truth to this? I thought the only level up from the SLT was the Denali. There's no mention of any derivatives of the SLT trim anywhere in the brochure, online, etc. Next question, if he doesn't know what he's talking about, will the factory override my selection and just put the 6 disc in there if it's part of the SLT package? Thanks for your help guys. I don't want to go down there and raise hell if the guy is actually telling the truth.
