I have been putting together the part list, if your have a digital Cluster already and programmed for it, I am some ware around the below:
$650-700 for the projector, cables, frame and switch
$700-$800 for dashboard from a take off Ebay need to find one cheaper.
???? windshield, there may be a work around with film overlay placement.
I just finished upgrading my Cluster to the LTZ/High country, found a take off for $200, sent it out to be programmed $200, for $50 more they will add other options and include the HUD programming as well so my cluster is preprogrammed for it.
The mirror camera upgrade is next, after that I might slowly start getting the parts for the HUD.
Need to find better pricing on the parts.
