Hold on, is the loom for a fixed BIT-II phone with the 54pin plug, that would explain it, it's wired differently for the BIT-II than the ULF (even tough its the same plug).

What year was the car that the loom came from??

I can find out what year it came from. But what you say mkes sense. I'll contact Bimmernav.

Don't connect it again it could seriously damage the cars systems.

Hopefully thats not why my car wont start up again. its asking for radio code after i removed battery terminal while doing another mod. We'll see. I entered radio code and doesnt work - i've let it sit for the 10min to 1hr has ppl here suggested and also BMW Assist. May have to send it to dealer to reset computer. But taht's another thread. LOL

There is a converter from BIT-II to ULF, it's cheap, bimmernav does them (I think), try that first.

Will do. So if i do this i don't need the amp? Sorry if this is redundant question to what you answered, just want clarification.

If you had the cd player upfront (incorporated into the radio), then the plugs are all up front behind where the radio normally sits.

When you retrofit it all get re-placed in the boot (trunk), but all the main connections are still where the radio was.

Yes had radio up front. I'll have connectors checked again.

The ULF does not have a sperate amp, it uses the radio module to amp ist output.

It should, but see above re the bit-II vs ULF.

It should, but see above.

OK - so it looks like my answer is contact bimmernav for the converter - and that may solve my ULF issues as long as plugs up front etc are plugged in correctly as well.

I does sound like the BIT-II to me, and other other faults you are seeing, deffo sound like they are related.

If the converter works the you dont need the amp, correct.

I agree, hopefully it should fix it.

Regardless of the outcome, I owe you a drink! thanks. Contacting bimmernav now.

Hey - so attached is what bimmernav showed me when i asked for a bit-2 to ulf converter. Should it have everything? looks like he's trying to sell me the entire harness right?

There is one that looks like what i need though. He quoted me $449 - not "cheap" like what you mentioned.. lol..

If you look at the BIT 2.jpg (bottom right or last pic) image the connector on the left (black with white 'clip' and blue inside) is what I have on my harness. Isn't that the ULF part?

ccfj1 · #15 05-20-2009, 03:16 AM

That's the whole retrofit harness, you don't need all that you just need the last pic, that's all.

This is the correct converter, plug <- this into the ULF and -> into your loom.

This is the only bit you need, it "should" be no more than like $60.

Buying the bits separately (plugs and pins) from the dealer would be approx $40.

So this mystery still isn't solved. But here's another loop - I have the TCU module (bluetooth & assist). Could this be the issue? Considering purchasing the bluetooth kit. thoughts? Is there a difference as well as the harness provided? thoughts?

rastaFarai · #17 05-30-2009, 03:20 PM

ccfj1 - thanks! You were right all along. BIT II harness and needed the converter. Got it today and it worked. Posting in someone elses thread the updates - but basically my bluetooth antenna range is no good now. any thoughts? when i'm sitting in the front seat of the car - the BT signal drops and bluetooth disconnects. before with my reg harness i could stand almost 10 ft away (it would activate when i'm at carwash waiting for my car). Thoughts?

ccfj1 · #18 05-30-2009, 03:30 PM

W'hoo, glad it's all working my friend.

Try extending the BT antenna into the cab, the OEM is only a short lead, replace it with the longer (4m) one from the e46, BMW p/n 61-12-6-912-541, and route into the cabin.

Any where under the centre console should be fine (or the glovebox).

Great info!! thanks again. Brian-BMW on the other thread i've updated mentioned plugging it in to the cream since i have TCU. but my TCU has bluetooth.
