I was wondering when replacing the instrument cluster, if there is a setting that has to be set for the NAV and the cd changer. I had my cluster replaced a few years ago by an indie shop. When I press my cd changer button on the radio nothing happens and same for the NAV but I don't remember if it happened around the same time as the cluster swap. I know it's a long shot but I'm just trying to troubleshoot what would cause the problem. Thanks.
