So for those who don't know, the 03+ models already utilize a dd unit, so all you need is the avg $20 dash kit. But unfortunately, to integrate with the databus controlled hu, you're also going to need the more expensive wire harness/module.
So did you utalize dash kits from pre 03 and 03+ to get the flush finnish? I'm thinking of tackling the same job myself, I usually wouldnt even think of cutting or trimming the dash but you made it look pretty easy. I just want to make sure I can get the nice finnish look.
