Doublecheck TCU Retrofit Plan
I have read through a bit of the numerous threads on the topic, so I just want to confirm that I'm understanding this all correctly. I have options S693 (sat radio prep), S645 (US radio), S640 (telephone prep), S676 (hi fi speakers), and S663 (pre radio). I think that all I need to add for bluetooth and for sat radio are the trunk boxes and of course the coding to make them work. I don't really need any advanced features with the phone - mostly just answering calls with the steering wheel - so I am reading this all correctly? Any reason I should go with MUFL instead of TCU?

a mulf 2 hi has usb .
But I would go with this it's much less hard to install and it gives you way more features. https://www.e90post.com/forums/showthread.php?t=1499808 |

I don't want to spend the time running wires for USB, so is there any functional reason for the MULF over TCU? Better BT, better call functionality, etc? |

No. The Mulf is a separate unit it could not do SOS but BMW
abandoned SOS on 2g anyway. You may have to program a TCU when you get it from another car. They don't always turn on all the functions and its voice recognition may be from another country and its Vin will be different. |

usb is nice for music library if you don't have any other method of storing music. ebay box has both usb , sd card for music storage and bluetooth streaming for music although the interface is kind of wonky. TCU gets you bluetooth phone(only) and voice control. Also some of if you can program modules on the Most Bus is dependent on the year of the car. Cars made after 3/07 require a more expensive Icom cable to program Most Bus attached modules. The think is a TCU doesn't give you very much.

So to confirm then, the only hardware I need for a TCU retrofit is the TCU itself, right? I've looked through those threads you linked and the only info I think I had missed was the different cable. Otherwise, I *think* I have it all covered but just want to check before digging in and finding out I wasn't as close as I thought. I have enough other projects, so this needs to be an in-and-out kinda job
