Again, stereo is what it is. If you have a old used E46.....Dynavin is the way to go if you want nav and a complete plug and play package. If you want to spend more money on the stereo, that is on you. Just remember what your car is worth and how long you want to keep it. I got a nice trade in on my E46 because of the Dynavin. Money well spent for me.
