I don't really have a "review", but I can say that the HK system in my 2011 ROCKS!

Life's too short! - No easy listening, country, or classical for me! My volume is usually set to max and the HK + iPod can handle things extremely well. Last fall we test drove a car with the base model and thought it was really fine, but it left me a little underwhelmed compared to what is in my '06 330xi. I'm not sure exactly what system is in the 'xi, but that one is awesome as well, and this HK with Logic 7 does equally as well.

Can't tell you price of the HK upgrade vs. an aftermarket upgrade, but I think it was definitely worth the extra $, without the hassle or possibility that something won't work due to the head being tied to the computer as someone mentioned.

Good luck making the decision, maybe you can find a car on the lot (or at a gathering) that has the HK so you can hear it?

Additional: I just looked at the amplifier in the compartment in the trunk in my 330xi. It says Logic 7 on the box so that answers that question, it's the same as in the new 128i. While I was there, I found a quarter way down in the bottom of the compartment! It must have been from the previous owner. You made it worth my time! LOL!
