You have all got to try this little test and see if my imagination is running wild or perhaps my hearing is playing tricks on me.

Set your radio to a normal volumn level and accelerate rapidly. Does the volumn rise a little at this point? Do not do this with the windows rolled down.

I thought perhaps that the volumn was being razed to compensate for noise, but with the windows rolled up this would not be the case. Besides, I have not read or heard that the radio is designed with this feature.

By the way, I took my car to a respectable audio dealer who informed me that to make our system into a first class system(like BMW should have done in the first place) would cost about $4500 and two days of work. This does not contemplate removing or altering the front end at all. I can only find 10 speakers in the car. I thought there were suppose to be 14. Could someone inlighten me?

Thanks,

Mark

the skinny on the street is that the system does indeed have a speed-sensitive (apparently not noise-sensitive) automatic volume adjustment.

it is very annoying IMO since the car is very quiet with the windows up at 100mph, and with the windows down at 100mph you can't hear anything anyway.

i have not been able to find a way to adjust it nor shut it off.

With the windows down at 100mph, you dont need to hear the radio......


yes- the system has some speed sensitive volume adjustment- very annoying for stop and go traffic, and it is not linear- it also makes some slight eq adjustments- as far as I can tell.

Someone posted how to adjust the sensitivity of the volume vs. speed on this site a month ago. I tried it and it works.

I keep the radio blasting at 120


On the note of 14 speakers, apparenty there are 2 rear speakers on each side. But that only puts the count at 12.

I believe I have the answer to 14 speakers. The rear sub-woofers are really two way speakers. This would possible account for two more speakers.

I tried to enter the service menu for the radio and forgot how. I want to turn down the speed sensitive volume setting. Does anyone remember what the "TP" button is on the US version and how to get to the speed setting. Thanks, Dave

I am counting that fact. 2 rear subs on each side, then two tweeters on the upper pillar, then the two midrange speakers in front, then the 4 tweeters up front. that puts us at a grand total of 12.

Dan,

Sorry to hear you missed the test drive for the upcoming meet. Tell them either they fix it right this time or you want a new car!!

Are you happy with the OEM music system? I got to tell you that I think it leaves alot to be desired. I had a good car audio company take a look at it and thay said it was pretty poor for such an outstanding car. The amps are not all that powerful and the speakers are of poor quality. Fortunatly this can all be cured without having to touch the front end. I would not want to get into any modifications that involved trying to seperate any of the integrated functions of the screen.

The fix is to replace the amps that are located on the drivers side in the trunk near the CD changer and replacing the speakers. It could cost anywhere from $1000 to $5000 depending on what you are really looking for.

Do you know anyone that has upgraded the system? Hope all goes well with the service shop.

By the way, I saw a bumper sticker that might be fun to have on the car when you take it into the shop. It reads "Keep Laughing I'm Reloading"!

I don't think all can be cured without touching the front end. I used to think that amps & speakers made most of the difference.

Then I put an audiophile-grade ($1200 Clarion DRX-9255) CD head unit in my last car. I was frightened at how much better everything sounded. I think the true fix would include replacing the changer as well or, if it's workable, putting in an outboard high-end D/A converter.

I think that replacing the changer would be viable, but I would like to know what the exact differences would be. The changer as you all know is really pretty cheap(ie CD holder). Why do they make cheap decisions like this?
