I am in the process of buying a non lux 6 disc to replace my current broken 6 disc and I would also like to do the LUX amp install at the same time. I know i am going to need to get the headunit reprogrammed for my truck (VIN) and also going to need to converted to LUX. I have been reading so many posts all this information is making my head spin. I guess my question is what exactly should I ask the dealer to do? It is an 04 extended cab with the premium bose.
