I'm not sure on the E60, but E90s made before around October 2005 had the MP3 feature disabled because of a hardware problem. Later firmware (V32 I think) was able to work around this hardware bug.
That would be pretty dangerous as you'd have to leave the other car running the whole time to supply the proper voltage (13.8 V or more--an idle battery only give about 12.2 max). You really need a professional grade power supply, not a charger, capable of 13.8 V continuous at 20 amps with the ability to handle spikes of up to 40 amps.
.. Actually, I have the mp3 functionality, and also the voice recognition. When you say I will loose Voice Recognition, and will need FSC code, can it be done as well? More colors would be nice
, however; wouldnt want to loose functionality.
BTW, would updating firmware help me hook up iPod (I want to replace the current CDC (CD Changer) with OEM iPod hookup
