[Zeros and ones]

I have that one in my e39 5 series and I love it. But you got to get the add on if you want the fill experience. The kenwood one pretty much is loaded with everything but at a cheaper price. Plus not to mention Garmin Navigation which is considered the best.

But you can not beat Alpine quality. With Alpine it just works. I have done countless updated to my ipod and every time I plug that into my alpine it works. My buddy has a Pioneer double din and I can not say the same about him.

Kenwood though is amazing bang for value. I do not think I have seen any other head unit come packed with so much stuff as such a great price. You really can not go wrong with this head unit.

My buddy has a JVC unit in his e30 318i and man is that thing rock solid too. What I like about JVC is that you can load up and play Lossless music files and if you are a audio-file you will enjoy that option very much.

I can go on and on, but you have to choose which one is best for your needs and budget.
