Dic Functions

[rx7srlife]

Ok so here is my questions. what are the standard DIC funstions withou steering wheel controls? Also could you get Personal and Business trip settings without having steering wheel controls? Im asking because When I bought my truck I had the dealer I purchased it from put a new cluster in it due to an inoperable oil pressure gauge. When I picked up, my only DIC functions were, Mileage,Personal,Business, and Hours. I was getting really sick of doing all sorts of math to figure out my fuel mileage. So I took it to the dealer that my brother works for and asked one of the techs to get me a trip function. When he plugged my truck in, the computer said that there was an update for it. he uploaded to update and I lost the Personal and Business functions. Is it posible that the cluster they replaced my factory one with when I bought the truck was one with full DIC funstions. I had read somewhere that GM produced every fourth cluster with Full functions even if the vehicle didnt need them for the trim package or not, because final computer cailbrations made the vehicle what it was when it was purchased brand new. If you can understand this please help. I really want the DIC funstions even though my truck didnt come with them. and I want to know if I can take it back to my brothers dealer and have the tech remove the update So I can wire up some switchs ad acess my DIC functions without having to buy acluster out of an escalade or denali.
