My 2002 had a production date of 11/01, and it does have the DB25 plug (pre-wired for cell), so the retrofit was very easy. I ordered kit #3 from Advanced Autovations. I also purchased the ULF mounting bracket for a factory clean install. I am pleased to say that the system works as advertised, and I am so happy to now have FULL functionality of all of the steering wheel controls. I also have the 16:9 nav screen, which makes browsing the address book etc...very easy. Total install time was less than an hour.
