The answer to that is very time consuming. To do it correctly requires removal of the dash, main dash harness, and HVAC main box. If you aren't basically an expert mechanic, I would not try it. I've been turning wrenches for over 20 years and after researching it, decided not to do it and just install the Raxiom unit. Of course, if you are mechanically inclined and this isn't your daily driver and you can be without it a few days in order to take your time and do the project then it's worth it. The Raxiom unit is nice, I have it. But it's not factory and the navigation menu's (not the navigation map system, just the settings menus) are very plain and difficult at times. If my car wasn't a daily driver, I'd probably swap it all over.
That makes sense. I haven't seen the full kit up, either.
