Navigation Wont Start
I just got a used 2006 e90 today. I have a problem with the navigation screen / radio. It wont turn on. Also I hear what i believe is the dvd still runing after i turn off the car.
I opened up the fuse box and removed and replaced some of the fuses. Fuse number 40 in particular, when removed stops the dvd. Any ideas? |

The dealer.
Did you check to see if the navigation worked when you bought the car? |

Oh boy.
I'm not a navi expert (my car does not have iDrive), but I'm going to guess that not having a DVD is the reason your navi isn't working. Your iDrive screen also contains many more functions which should work regardless of whether a DVD is installed (I could be wrong on this). It looks like a trip to the dealership is in your immediate future. |

The 2006 with the iDrive had two disc drives, a CD on top and a DVD on the bottom. The DVD was used for the navigation data disc. Whether a disc was in the drive, the drive always sounded, very quietly, like it was spinning even after the car was turned off.
If the navigation and radio are not turning on then this is a symptom not of the navigation but of the iDrive itself. It can be caused by a number of things (from my experience). One is an incompatible cell phone paired with the iDrive. Another is simply the system needs to be rebooted. A third is that the TCU is kaput. The first thing I'd try would be a reboot. This is done by holding down the mute button on the left of the CD drive simultaneously with the eject buttons for both the CD and DVD drives, aka BMW three finger salute. Barring this being successful, as methodtim stated, a trip to the dealership is in order. I do hope you have a warranty for if it is the TCU then I understand a new TCU costs $1200-1500. Supposedly, an incompatible phone will damage the TCU. It would be nice if someone in the know could finally explain to the BMW public how a radio connection and software handshake between two devices using an international standard can cause damage to one of them.

The iDrive should work without the nav dvd, you just won't be able to access navigation related stuff. Mine was replaced under warrnty, see this thread and this one for more info. The second one has a service bulletin number and info that may be related to your issue.
Is the car still under warranty and honoured from where you live considering you imported it? If so get it looked at ASAP. The error I had the iDrive always worked, although it did start rebooting a lot during driving (which took out the radio during the reboot), but it always came back. I don't think the iDrive is too well built. As these threads state I had mine replaced/repaired under warranty around a year ago and I'm starting to get the early signs of it going out again (insert map dvd message popping up when the dvd is in). I'm just glad mine is a lease and I'll be returning it soon, after this experience I wouldn't buy (as opposed to lease) a BMW with iDrive. |

Regarding the international standard, you are making a (somewhat incorrect) assumption that the device maker is adhering to the same specs as BMW. Bluetooth has a lot of wiggle room in the standard (based on how you deploy profiles and which profiles you choose to deploy) so hopefully you don't believe that all Bluetooth devices are created equally.

If that is the case, with regards to Bluetooth standards, as you've stated then there is NO Bluetooth standard! When all manufacturers adher to a single agreed upon set of interfaces and the manner in which they function then the incompatibility issues will evaporate. None of this "wiggle room" crap and selecting what subset one wants to abide.

If you read my tests of Bluetooth phones, you´ll see the wide variances in compatibility and the truly weird problems that cropped up, such as directory names being completely mixed up and jumbled (i.e. a few different names were chopped up and reassembled=.

In case of incompatibility, the devices will not pair, but neither of them is supposed to crash. In case one of them did crash, the device that crashed, in this case the iDrive, has failed, since it contained a built in design fault. The iDrive in question seems to have yet another problem. A modern, well-designed electronic device is supposed to recover from any failure by itself, or by simple assistance from the user. Most people who contribute to this forum can repair, and for sure reboot their computers, because computers are designed to allow for this convenience. It is strange that when it comes to rebooting a rather simple processor-based device in their car, the same people have to spend hours of time and often sums of money at a car dealer. BMW does not sell to the car owners anything close to e.g. the documentation available for 802.11x or any comparable standard. If they did, we would not only know pretty quickly why the iDrive failed, for many of us the pleasure of owning the ultimate driving machine would be heightened to the point of unsurpassability. |

While it´s true that iDrive did not graciously recover from the crash, two engineers from BMW AG agreed with me in blaming the mobile phone (Samsung brand).

This looks like trouble. Is there any clause in the contract regarding the condition of the car? The navi system is nothing very complex, and what is often called the media (CDs, DVDs) should have been included in the shipping. If you cannot get it, you will need help from a dealership. Read though the thread, there are quite a few good suggestions there from people who have the same iDrive as you do.

Still, we are not talking here about the car as such, but about the performance of the iDrive. My first point still stands: a higher level device has to survive any interaction with a lower level device - this is how systems are built. A cheap Samsung phone should not bring down a BMW car - if it does, the car electronics is under-designed, and the problem cannot be talked away by blaming Samsung. The new iDrive is of course a good news, but it is also a demonstration that there were too many problems with the old system. My second point goes beyond the phone problem: There is no satisfactory documentation for BMW cars available from BMW, for the car owners who might want it. All the technical problems discussed on this forum are already known in Munich. It is unfortunate that a shop manual, in any language or form, is not available. |

The 4th generation of iDrive was developed from the knowledge gleaned from the first 3 generations. In addition, you can't lump all three generations of iDrive into "the old system" as there were more differences than similarities. Finally, while previous gen. units had issues, the percentage of units that failed has been exceptionally small and that is in direct contradiction with "too many problems".
