Thanks again for all the info...where do you find all this stuff! I think I'll leave the 21 codes alone as out of my league. I also tried restoring the OBC info in the instrument cluster by pushing in the BC button on the turn signal as suggested, but no "prog 1" appears. I tried various key setting combinations while holding in the BC button and never got the prog 1 indication to show up so dont know what I am doing wrong.
You had mentioned earlier that a priority 1 warning would wipe out all info so obviously that was what happened. Is there something I am missing to restore this info?
