Is there an official BMW policy on the use of USB flash drives?
I use a 16gb flash drive to store and play MP3's via the 6FL USB port in the armrest. Since BMW so kindly provided me with both an iPod cable AND a USB cable, I figured there would be no problem doing so.
It works fairly well... every now and then it suffers a little hiccup and has to be re-read (just have to navigate up in the iDrive menu and re-select it) but for the most part it's great. When I was casually discussing how I liked the car with my sales guy and SA at my last visit, they got real upset when I mentioned the flash drive and said that the USB port is for iPods only and using a flash drive could screw up the car and that I shouldn't use it anymore. This sounds like a load of crap to me. BMW specifically provided a USB cable which has no possible purpose if it were only to be used with iPods. Does anyone know if there is an official policy or bulletin or anything else on this? |

What about the USB port in the glovebox?
IIRC the owners manual correctly, the USB port in the armrest is for portable music players (like the iPod), and the USB port in the glovebox is for flash drives, etc. I don't know why it would make a difference (other than the armrest providing power to the iPod).

Just get one of these.
http://www.newegg.com/Product/Produc...82E16822136228 They come in 160gb, 250gb, 320gb, qand 500gb. Ranging in price from $80 - $180. I have a black 250gb and its amazing. Absolutely love it, and they run off the power from the USB. No external power source needed. Plus, then you could store up episodes of Top Gear, movies, or a rediculous amount of music. Whichever suits your fancy.

Odd that the M3 USB port doesn't provide as much power. I also haven't tried to use it in a M3 yet. But for all other applications, its worked just great.

I don't think it has anything to do with the idrive system. It's the limitation of the amount of current available through a USB port. I believe it is 0.5 amp max. These external hardrives draw less than that at their steady state but at startup, there is a large draw to get the motor started and that draw is typically larger than what is available. That's why if you read through the thread a lot of guys are saying the drive light is on but the motor is not spinning. There just isn't enough juice there to startup the drive. When used on a computer, the drives are typically supplied with a 1:2 USB pigtail so that you can connect to 2 USB ports at the same time and doubling the amount of current available.

Already knew that. The real question is why. How does it differ from a high capacity flash drive or an iPod since an iPod is considered a storage device too? My previous explanation is the only possibility I can think of.

the previous post is correct... it's the startup current to spin up the drive that is actually quite high momentarily and USB just won't cough it up, as it has current limiters.
But flash drives are absolutely no problem and should be the way to store all your tunes and movies. BTW, you could use an HDD like the newegg product and plug it into the power port in the 09 armrest console... it could be done that way. And I think the CA/SA are nuts on getting upset about a flash drive... if you can't plug an flash drive in... then what the hell else would the USB port be for....? |

Thank you for sharing this. I wasn't aware of the 1:2 pigtail to get the spindel turning.

Big difference between external hard drive like the WD passport and flash drive. External hard drives have a platter inside, that spins at various rpms. This obviously, requires more current to run. A USB flash drive, has no moving parts inside, and therefore, requires less current to run.

Any idea why I can play music from my flash drive in the USB port in the armrest but not from the glove box? It doesn't show any USB connected when it's in the glovebox, but my flash drive lights up.

The one in the glove box is to go and save music in your harddrive. It is not for playing music, but rather to download.... Hope this will help...
