This thread needs to be updated with all the audio gadget options.
I have spent hours upon hours looking through this forum and still cannot identify what options I can or can't retrofit - USB, Ipod, Bluetooth streaming, etc. It's so confusing, and just when I find a thread that looks like it's making sense, people are saying "its not released yet" and the thread is dated 2008 or 2009... I still haven't found anything that makes sense. Everyones using code names and there's no where that explains them. 6NR 6NL 6FL MULF2 TCU CIC CCC CDC MOST i-BUS SA644 SA640 SA609 M-ASK... wtf is going on.

My E90 has a Sirius module and the TCU which gives it Bluetooth. Also has an aux input, but no USB. Looking to add USB at some point in the future, and it seems I can add the MULF and replace my Sirius module with it, move the pins to a new connector for the MULF, code it, and be done. I think.

Please understand that I do have a basic grasp of the various audio systems and some of the modules (read the stickies). Then you have people referring to the same module with multiple names (TCU, MULF, MULF2, MULF-hi, etc).

Fyi TCU and MULF are not the same thing. TCU is normally associated with bmw assist and bluetooth, whereas the MULF is used for 6FL, USB& iPod interface. It also happens to have a bluetooth capability that some people have tapped into, but it doesnt come that way from factory. |

I know the TCU and MULF aren't the same, I'm just throwing the acronyms out there. For reference, my E90 has a TCU as it has Bluetooth and BMW Assist, as well as the aux input, but no USB. I know the MULF can do all the functions of the TCU, but that's about as far as I've gotten. I've actually been chatting with another member here about it, and he has seen (read) something about someone running the TCU and MULF in parallel. Of course coding was required and I believe repinning the TCU connector was necessary. I hope to attempt the retrofit eventually, but time and funds haven't quite lined up.

There needs to be a separate thread for features
There needs to be a separate thread for features
like blue tooth audio and some of the newer internet options this was intended for sound quality. |

Well nobody has taken the time or has the knowledge
Well nobody has taken the time or has the knowledge.
Or all the knowledge and it really hard to get things stickied here. Or almost anywhere I guess. Also since this was suppose be an informational thread after the first two or three pages is has kind of degenerated into a ask questions thread which I don't think it was intended to be, especialy since a lot of the topics are not about sound quality and how to get it. The bluetooth sticky is the closest thing buts it's all OEM It looks like this board needs more sub boards. Like maybe a bluetooth and Internet sub board. |

thread doesn't deserve sticky until it's fully fixed
the stuff about replacing with an aftermarket head unit isn't necessarily true (could be different in the USA) - plug and played no worries in the few i've seen. (all bongs, steering wheel control etc.) nor does it even list USEFUL things like the mounting depth of the stock underseat speaker (54mm, as far as i'm aware) imo it's just so much easier to ditch everything factory, and get a proper sound system... too few people bother doing this. |

If you want to do Head Unit is should be separate
If you want to do Head Unit sticky it should be separate
because its and entirely different set of problems. This was intended for sound quality upgrades. Also a separate one on subs would be good. |

I recently built an ipod interface that works with the cd changer connection in the trunk of my E90. As soon as I get all the bugs worked out I will post a DIY. The most expensive part of it was the coding required.

Ideas to Upgrade
Hi,
I am new here but I have done upgrading on various other cars. I have a question about upgrading the BASE system. 1. I understand that the Under seat woofers and front speakers are in parallel?? Correct? 2. The high level signal coming to the woofers would be full range? Correct? But will be EQ-ed by the HU. So instead of using harness etc, would the following method of upgrade work?? 1. Tap the signal from the input of the woofers. ( obviously disconnecting the Woofers) 2. Run the left and right tapped signals to a processor that performs summation and EQ if required. I believe that would give full range. If the processor requires more channel input, then just parallel the inputs to the other Processor inputs. 3. Run the Processor Output to a 4 or 6 channel amp. ( depending if you still want the rear speakers to be powered). Disconnect rear speaker cables if not using 6-channels. 4. Disconnect all speaker connections and run new cables from each speaker ( front, underseat and rear) to the amp. At this point you could change speakers to whatever you like. Would this work?? Drawback is: 1. Some signal tapping required but would not really be a big issue as the cables would not be close to the HU and only those that are closer to the stock speakers. 2. Extra speaker cables need to be run to the fronts and rears ( if used). My plan was to just go for a 4 channel compact amp and forget abt the rear altogether. Is this a good plan or am I totally off the mark? |

Edit: if you run new underseat wires you can tap back into the vehicle harness which ultimately goes back to the doors |

He uses vehicle harness to connect HU to DSP, new underseat wires to connect amp to underseat, so he need to use new wires to connect amp with midranges in door.
