Gettin antzy and excited to start my retro fit.
So far Iv gathered ill need a TCU,(84109149615) thanks ACE and Stuartjohn. Ill need a later model MMI aka facelift. plugs for the fiber as well as the 54 dongle. And a decent batt charger for the flashing end. Now whats gotten me scrathing my scalp is the flashing and software end as to which program is easiest or best. NCS, tool32 and ACE's Dashsoft. Well still reading, like I said got excitted and wanted to join up and speak up. Great works guys, signed green with envy

Welcome to the world of BMW coding.

As my car is a face lift I had it a little easier since I only needed to replace the TCU and flash the MMI, but I'll comment on the software.

I don't believe there is anything Dashsoft can do that you can't do using a cheap OBD cable and the "free" (*) software available on the net. I have been using NCSexpert, NCS Dummy, Tool32 and WinKFP with great results.

As for power supplies, I am convinced BMW's 70A requirement is wildly exaggerated; I use a 50A ham radio power supply (see my earlier post in this thread) that cost me 118 euros and it works great.

(*) I am actually a little bit concerned about this; I work in the software industry and I have lots of friends in the music industry so I am always careful to respect copy- and intellectual property rights. I doubt BMW intended for their software to be distributed and used the way we do now. Not that it keeps me awake at night but I think it deserves consideration. And even though I use the software on occasion, I will not re distribute it.
I've been meaning to find out exactly if my use of the software actually is in breach of IP rights but have not gotten around to it yet.

Hello guys.

I want to upgrade to Bluetooth ( I currently have the cordless handset in the front drawer). I know I will need some coding but do I just replace my Siemens AT with a Bluetooth TCU from any E65 as long as it has Bluetooth ( I have facelift mmi and ask)

Thanks very much

Pretty much, yes. As long as you make sure the TCU you transplant is recent enough to have the full Bluetooth implementation. Try to get one manufactured later than September 2006.

Thanks very much. Will any make do (Everest / continental etc)?

Thanks again

Will a tcu from an e63 fit or must it be from an e65. The part number I have seen for sale is 8410917775402

Thanks

Any ideas please???

Thanks

Phil not been funny but u need to read this thread from the start it will explain exactly what to do from start to finish especially where to get the proper connecting plug from and how and wat wires to change over etc and how to code it ,it is quiet easy to do but a lot to explain .wat I done was had the page open on my laptop that shows Stuartjohns post on how to do it in this thread .

Thanks irish745, sadly you will have to do some reading! You will need the new connector, I got mine from an audi dealer, BMW didn't stock that connector for some reason.

To give you a hint start with post 243, I listed all wiring for a UK Siemens to Bluetooth TCU conversion. The next page shows the installation and coding process. I did list the part number for the connector too on one of my posts around there.

Sorry guys. I was just keen to get it done and panicked a bit. I'll read through properly first

'Best to remain silent and appear stupid than to open your mouth and remove all doubt!!'

I'll let you know how I get on

No problem at all mate. I didn't take it the wrong way and appreciate all advice given

Excellent thread!

Really wish I read this thread sooner, then I would have kept my TCU from my 2007 e90 after upgrading to combox. To add insult to injury, through the combox upgrade, I had to reconfigure the 54 pin tcu plug to the 26 pin plug the combox used.

Ironic isn't it, we went from 26 pin to 54 pin and now back to 26 pin...

Anyway here is the part# for the 54 pin if you want to order from BMW instead of Audi: 61136920074


EDIT: Just heard back from Evan@Tischer:

I believe you'd probably need all of that to build the appropriate connector for these.

Let me know if ya need anything else! :thumbsup:
