Bluetooth retrofit w/vr for oem nav?

[velocity_b]

Hey guys

So I want to do an oem b.t. retrofit in my 04 ci that will also add v.r. for my oem navigation system.

The car came with bmw assist and from what I've read all I have to do is switch out the assist module for a ulf module and add a pairing button, correct?

Does anyone know if there is a specific ulf unit that I should look for, since I am looking to add voice recognition for my nav too?

Thanks!

Lots of info out there and I don't have the details, but I do know everyone always says get the latest module you can. The # is around. Check out xoutpost.com or e46f.c.

Yeah, I'm trying to sort through all of it to find the last generation that still works with an e46.

If you want VR to work with OEM Nav, you need a ULF, not TCU.

TCU / Assist combo units do NOT have VR that will work with OEM Nav. No way to change that with clever programming either.

13th gen TCU part # is: 84109154358

I've extensively documented the process here, as well as the difference between a ULF and TCU.

But IMO, I would go the TCU route over ULF at this point. The TCU was updated last year and works with all the latest iPhones etc. The ULF hasn't been updated in a few years, requires a discontinued pairing button. Plus, the VR isn't that useful anyhow. Remember, this is essentially a 10+ year old Nav system at the core. The VR works for basic commands like "find gas station" but beyond that it isn't very useful...

Thanks guys!
ULF doesn't really seem worth the cash.
Looks like I'll be going some sort of aftermarket route...

What are you looking to do? The OEM Nav with updated maps + updated OS + Bluetooth TCU is a very good system. And will certainly most reliable solution.

I'm looking to add bluetooth(I have assist) the voice commands of a ULF are a nice bonus but all the ULF's I saw were going for over $600.
Looks like for $250 I can go with the Argos B.T. which uses the factory B.T. wiring and will work with my steering wheel in an oem fashion.
The VR for NAV would have been nice but not worth the extra $400 imho.

Read my thread I posted above.

Why waste your money on an aftermarket kit, when you can replace that Assist unit with a Bluetooth TCU / Assist combo unit for $338. Since you already have Assist, you have the microphone, mounting kits etc--you just need a new TCU (they take your old one as a core). OEM, direct plug and play. No way an aftermarket kit works as well / integrated as this.

Just order this part #:

Couldn't agree more with everyone else on sticking to factory bluetooth. Retrofitted it to my E39 without issue and enjoyed completely flawless service. Saved the unit which I'm going to stick in my fiance's ZHP.
