Yea I'd do the install of the BT myself, I just need the part numbers. I let the dealer do the xenon swap, they charged me 1k for install, footwell module, and programming. They are currently looking at adding another wire today to make the highbeams work properly. Once thats done my xenon swap will be the first done that are fully functional and w/o an error.
The bonus about letting them do the xenon swap is the tech did a better job then most of the people who did them on their own. He got a faulty harness and used the plugs to add the wires. This way everything is completely waterproof and looks perfectly stock. I feel the 1k was more than worth it.
