Logic7 vs. standard stereo by maril556

Can somebody describe a difference b/w Logic 7 and the standard system in 535i?
I have 545i with Logic 7, so I know what it is. I'm just not clear about how basic system is different?
Different head unit? Different speakers? amplifiers? subwoofer?
I do realize, that the basic system will not have various surround mods and an equalizer.

ODOMETER by eastburg5

Hi All,
 
I recently placed a down payment on a 2001 525 BMW from a non-BMW dealer. The vehicle has 17,300 miles, but the rear brake pads are worn down and it looks like the front pads have just been replaced. Skeptical of the mileage, I took it to a BMW dealer who checked the mileage on the key FOB and it indicated 17,300 miles. I do know that the one previous owner drove the car in the city. My first question is whether its likely that the brakes could be this worn in so few miles? Also, I was wondering whether key FOB is an accurate indicator of true mileage, or whether it simply repeats what is on the odomoter? How difficult would it be for someone to turn back the mileage?
 
Also, I've heard that its usually necessary to replace brake rotors when the pads are replaced. Is this true, or are there ways to replace pads before the rotor is worn?
 
Thanks!
SRE

Sounds like a jack rabbit start and hard braker to me. You've seen those guys on the road. Sounds like the car may have had 17,000 rough miles even though it took 7 years. The other side of the coin is he/she lives in a very steep hill environment or just rides the brake often:)

17K miles in 7 years, sounds like a lot of stop and go, city driving...
 
There are plenty of BMWs that need pads/rotors by 30K miles, in a normal driving environment.. The braking capability (and all that nasty brake dust), come from super-soft pads..
 
So.. 17K is early to get brakes, normally, but 2500 miles/yr isn't exactly normal..
 
BMW specs say to replace rotors with pads... but, most do-it-yourselfers replace them every other time..
 
If you are confident in the mileage being accurate, I wouldn't let new brakes bother me...

Only if a dealer does the work. You can probably get away replacing the rotors every other pad change. It's a dead easy DIY job. I'd go to Zeckhausen Racing and buy Axxis Deluxe Advanced pads. If you need a full set of pads and rotors it will only run $350.

In addition to surround sound processing, the Logic7 system has 13 upgraded speakers and 420 watts of power. Compare that to 10 speakers and about 200 watts in the base system.
 
Also note, the surround processing logic was designed by Lexicon, which is one of the higher-end home theater and AV electronics shops.

I just looked under the hood of a 2008 535 and didn't see a dipstick along the firewall as described in earlier posts about the 550i. That doesn't mean that it's not there, just that I couldn't find it.
 
The owner's manual is silent on the subject. I also see posts that other 2008 models like the M3 that will only have electronic oil level monitors. Looks like a trend.
 
If some engines have dipsticks, my question would be why does BMW treat their existence like a state secret? My only guess would be that these newer engines are so complex that they just don't want owners fumbling around in the engine compartment.

Thank you,
I actually went to a dealer yesterday to listen to a standard sound system.
Absolutely day and night compared with my Logic 7.
Ended up ordering 535i optioned, like we wanted to, Logic 7 included.
It is now $1200, vs. $1800 in 2005, when we bought our 545i.

A manual dipstick isn't too much to ask. I wonder if BMW listens to the suggestions in these forums? And don't we all feel just a little foolish learning that there actually is a dipstick, although BMW protected that little secret better than the CIA.
 
I recognize that the original intent of iDrive was to provide greater granularity of control while uncluttering and simplifying the dashboard. And I recognize that some of this technology is just a marketing ploy to lure us into buying expensive options like "night vision". That's why I always custom order BMWs only with technology options that have some utility.
 
The question should be: can BMW continue to advance performance and handling while improving fuel efficiency without all these systems intervening between the driver and the vehicle? Some BMW engines are pure racing technology and I do know that they require extensive controls to make them reliable daily driving machines, but is this the only way it can be done?
 
Performance is improving. Handling generally is improving with less trade off on ride comfort. Fuel efficiency is improving relative to engine size and performance. The vehicles generally are safer to drive. So in general, the vehicles are "better" by those measures. But I agree that BMW should ask itself whether they really need all this complication to improve the core competence of the vehicle.

Picked up an 08 535i by troysb

Just picked up an o8 535i. Had a 2007 530 but BMW couldn't fixed a problem with a consrtant battery drain. I made a fuss and they gave me brand new 535i. I had a silver and I opted for a white. So far the twin turbos are so much better that my old 530. Still can't stand the run flat tires. it is a hell of a bumpy ride, especilly in Manhattan. I also opted for the sports and premium options. Didn't get the cold weather, just got the heated front seats, didn't need a heated steering whell and fluid to spary my headlights. I would also recommend that anyone get the option for thre repalcement wheel and tires. rims are too expensive, especially with the run flat tires.
