I listened to the Logic 7 system in a 330i recently at the dealer(The radio came on without the key!
) and I wasn't impressed. It sounded good, but the true test for me will be with the car in motion with road noise to overcome and my favorite music turned up a little. I should add, however, that my current car as an aftermarket system by Alpine so it's unfair to compare apples to oranges.
