Connecting Linux computer to BMW 328i (2009)

Is there a way to connect your computer to the USB/AUX ports on a BMW to stream music?

The USB works with thumb drives fine, but it's a PITA to filter which songs I want, so I figured if I could use a netbook as a controller or DJ, it would help a lot.

Is this possible?

Any experiences?

Any other IT people here?

You can connect the MIC out on the laptop to AUX in.
I don't quite understand what you are trying to achieve.
Are you trying to mount your laptop hardrive as a USB device to your car's stereo? Unless you make your laptop behave like a removable media w/ appropriate file system format - e.g. FAT32 formatted USB stick - I don't think you can do it

Well, yeah. I want to use the media player software on the computer to browse my library of almost a TB of music. I have it sorted with cover art, etc, all OCD like.

Yeah, the AUX is the worse case, but I was hoping there was some software that creates a handshake from the laptop to the ECU/BMW computer.

I know it's a long shot, but worth a shot.

You can make a partition with gparted http://gparted.sourceforge.net/ formatted for FAT32, adn then research on how to make it into a mass storage device.

If you are trying to just play music from your laptop thru your car's audio system, using the laptop as the controller, then I think the aux port is all you've got. The car can't mount your computer HD through a USB connection between a USB out of your computer to the USB in to the car. Besides at that point (if it were possible) you would be using the car as the controller which is not what you are wanting anyway. If your car supported Bluetooth streaming (which is natively doesn't), you could do it that way. I can do this in my 528 and do it all the time with my smartphone. I bet you can buy a bluetooth device to connect to your USB port, if your car supports audio through the USB, or to your aux port and stream audio that way, with a bluetooth equipped laptop.

According to these http://superuser.com/questions/42709...e-mass-storage
Quote:
Host-side USB and peripheral-side USB are controlled by different hardware. Your PC has a host-side interface, and so does your TV. Your flash drive, phone, etc. have a peripheral-side interface.

You can never connect host-side to host-side, or peripheral-side to peripheral-side. The hardware doesn't support it. ("USB To Go" changes this but read on.)

I'm not sure of any Windows software that implements a mass storage interface over USB, but there is such software for Linux; Android and WebOS phones run it. But the software won't function unless the hardware USB chipset supports peripheral-side. (I'm not sure how the new "USB To Go" spec affects things but you would need hardware and a driver to support it.) Not sure how installing something like this would work.

You could possibly cobble something together with a rooted Android phone but I am not sure how it would work. There's apps for Android that expose the SD card via Samba over Wifi, and then you could connect the phone to the TV via USB. Have not tried it myself and I don't know if it will work.

Regarding your link above, Firewire is a more sophisticated and CPU-independent protocol than USB. USB (unless new "USB To Go" features are used/implemented) can't operate without a host controller orchestrating things.
So it does seem like an impossible idea unless your laptop supports both host-side and peripheral-side USB interface.

I actually was on a similar page.

Bummer!

Next solution: External TB hdd I guess and power inverter.

Why not something like this:

http://www.amazon.com/iKross-Bluetoo.../dp/B00917OWYI

Bluetooth streaming quality sounds pretty good to me. Of course this is thru the aux input which you don't like for some reason. What's the quality problem with using the aux input?

Also not sure about the linux and bluetooth transmitter end of things. Does your laptop have bluetooth and are there linux drivers for it? Otherwise you may have to revert to windows possibly as a virtual machine on your laptop.

No real need for a power inverter if you get something like this:
