I have a 2001 Impala LS, it didn't come with any FOBs, since it was a REPO. I have fobs for it, but I can't get into the settings menu on the radio to program them. The last Impala I had a few years ago I was able to, but it was a base model. I'm not sure if I need to do something different other then key to ACC and hold the DISP button on the radio until it goes into settings. Is there another way to get into it?
