2007 X3 ULF bluetooth retrofit (part 2)

4. install eject box in arm rest

Lifted up the rubber cover, loosed the 4 torx screws that hold the trim piece in place

Used a little bit force to pull the trim piece up. It came out easily. Put it away. It's not needed any more. The new trim piece is used to finish the installation. Following pic shows the wiring harness for eject box

I used a tiny nail to push on the 3 clips to release the connector from its seat. See following pic for a close up. After connecting the wires, I latched the connector back to its seat. It's a MISTAKE. Instead it needs to be tucked in a corner to make room for the eject box. It's a whole lot harder to unlatch it again after all the wires are connected

And a final look. I didn't purchase any cradle. The part comes with an empty tray in place which is good to store some small items like keys, coins. I was really puzzled by the only button on the eject box with a bluetooth symbol. It turns out that it functions as both a pairing button and a eject button for the cradle (or empty tray in my case).

5. install ULF in trunk

Before doing anything, write down the pairing code that's shown on a sticker on the ULF. Open instrument panel on driver side by pressing the button on the wall.

It was straightforward to locate the 54-pin connector for ULF. But I wasn't sure which one is the BT antenna connector. I found two connectors in creamy/purple color. I didn't trace the wire to find the BT antenna plate. Too much work. By trial and error, the shorter one worked for me. But there is slight static noise for voice coming off ULF.. Anyway, here's the pic of the one I used:

The one that didn't work for me

Finally found 2 screws from my toolbox to fasten ULF to the mounting bracket.

My car recognized the ULF when I turned on ignition. An entry "telephone" is automatically added to the screen. No dealer coding required!

6. Pairing

To pair my phone, I started with engine off, pressed and held the BT button on eject box, waited couple of seconds, turned on ignition, waited couple of seconds, released the button, my car entered pairing mode. Everything went smooth after that.

7. usage tip

Press and hold the talking button on steering wheel for about 1 sec, after hearing the beep, say "help".

8. things I like

Phone paired without problem. View all contacts from nav screen. Voice quality is pretty good, except for a slight static noise in the background. voice recognition is pretty accurate. Can read SMS on nav screen.

Hope someone found this useful.

07 retrofit TCU or UFL confused

Id like to retrofit my 07 with bluetooth in order to listen to music and operate the phone. After reading the archived threads im confused on what is the simplest route. I dont really need voice activation but also dont want to have to code anything. My understanding is that what you can install depends on the cars prewiring. So i got into the rear panel and looked around. Here are the leads i found. Can you guys tell me what my best option is to complete the retrofit.

What you found is for the Sirius radio module is in the first photo with the soft piece of covering around it.

the Telemetrics module sits at the bottom of that compartment, and there should be several wires down there if you are pre-wired.

That is the module and the plugs for it. so you need 4 plugs that fit the antennas, and a big plug that looks like the other end. they should all be at the bottom of that compartment. or can reach down there easily.

And dont think you are going to get music. It's for phone calls only, the music will not work as A2DP bluetooth music is not supported with BMW OEM bluetooth.

Ok

Is that a AFL or TCM? If the OE doesnt support music then thats a fatal flaw since that's what the goal is. Well @ least i didnt spend any $$$

The connection from ULF to HU is mono. A2DP is not supported.

This is my solution for bluetooth music and it works flawlessly.

From what I can tell there aren't many USASPEC units left.

Thanks for the info

I bought a HTC stereo clip that uses the 3.5 aux jack to transmit music over BT with my moto X phone much like the tune2 unit. Sounds good and it pairs when i start the car. I still have to select the music and it doesnt pause - restart the music when the cars turned off and back on which is a hassle.

Id love to install a aftermarket HU and be done with it but they ruin the interior lines of the dash-center counsel IMO. I noticed GROM offers both hard wire and BT units that works like the USASPEC unit for around $150. I think may be the route to go.
