2003 E53 with ULF

Good Afternoon everyone,

I am new to the forum, I just purchased my 2003 X5 4.6iS 2 weeks ago.
I thank all of the contributors on here for all of the details and fabulous information. I am a forum moderator for a BBQ forum, and I truly know how much time is spent in the threads

When I first got the car home I opened the glove box to read through the manual and I found the BMW ULF manual (yeah) with a card containing the passkey.



I read through the pairing instructions and gave it a couple of tries step by step (I have the telephone button in the center console). Both of my phones (Android and iPhone 4s) did not see the car. They aren't any lights on the radio (factory NAV) and nothing happens when I push the phone button on the radio.

I went to the back to make sure I actually have the unit in the car, check.



I pulled the battery for almost and hour and I read on here to check and pull fuse 73 in the back (which I did after reconnecting and testing).



And still nothing at all??

Is the unit pooched? Any other testing I should try? I am considering a GROM unit for USB music (and bluetooth), but thought I would try to get this working if it exists first.

Thanks,

Che

Am I looking at the right spot for the fuses, the bottom label is faded and hard to read? What are the empty slots for?

First off,

In 2003 BMW made an error in shipping the Bluetooth manual and passkey. In fact, the Bluetooth functionality didn't exist on cars from the factory that year. There is a lot of good information on Bluetooth retrofits here - http://www.xoutpost.com/bluetooth.php

Also, do a search as there are folks that say that a TCU is a better retrofit option than the ULF.

Thank you, but it has the ULF unit in the back and the bluetooth antenna wraps up around to the top of the entertainment stack (above the disc changer)... etc.

Is it possible it has already been retrofiited by the previous owner?
It had the telephone wiring, etc. from the factory. There is even an older phone adapter for the center console in the glove box.

Yes, it is possible that a previous owner did a retrofit (or attempted one and gave up). What is the part number on the ULF installed in the rear?

I can't read it in the car like it is, it is upside down and covered. I will have to remove some things to see it better.
