I, too, was reluctant to change anything on my 2004 Pacific Coast Special Tbird but the state law changed here in Texas so I really needed the bluetooth for phone calls in my daily driver. I carefully saved the original radio for my grandkids if they ever want to restore it to the car when they inherit it. Like others, I bought a double din replacement radio, and the facia trim kit, and the harness adapter, and the backup camera. I selected a JVL Kenwood but as an electrical engineer, I know all radios are built from the same hardware items and it is only the features and the firmware, or programming, which varies between a $200 unit and a $2000 unit. On line videos and the owners manual and wiring diagrams and comments on this forum were a big help. One word about picking your unit, DIN is a great standard and any double din radio will indeed fit. Search the internet for the features and price range which fits you. I did not bother to reconnect the steering controls as I do not use them as a matter of course. I am still working out how to precisely connect power to the backup camera as it seems to me the reverse transmission mode is communicated to the Rear Electronic Module by way of a CAN buss signal and the backup lights are hot all the time and are switched by the REM sending out a switched ground return path. For power, I can easily access the backup light fuse professionally in the Rear Fuse Box, but I am puzzled as to which place to access this switched ground. Once I find it, I will need to select a suitable relay which will not confuse the " illumination bulb out warning system". ( I found the hard way that installing New High Tech LED turn signal bulbs is a no no on that account.) One other open issue I have is that facia trim kit seems only to be available in Black or painted Silver. The PCR has a gray panel and it would have been nice for someone to offer to supply a gray radio facia trim panel.
