Man, i really wish i had the navigation unit in my car. All the aftermarket units make the car look so awkward. nothing beats the stock look. Is there any possible way to retrofit the navigation? If not does anybody know of any good aftermarket units that'll fit in my 2004 325ci. I want to get at least a 6 in. motorized lcd, and dvd player. Then maybe later add a navigation and tv tuner. Broke right now but doing some research before I start saving up for one. Panasonic had some cool ones but they dont really lok that great and were pretty expensive. Any thoughts?
