URGENT PLS, i need quick answer
 

hi guys, my story as the following:

my can is X5 2003 3.0, i have pre-installed BIT II phone and i upgrade it to bluetooth (snap in- antenna and antenna cable-ULF bluetooth 13th GEN)

before i install the uls bluetooth (already remove the BIT II ULF) there was a telephone on my screen, i upgrade the navigation to the new firmware then i loose the telephone on the screen, after that i install the blluetooth ulf, it didnt work, then i went to BMW dealer in kuwait to retrofit it, they call me today and said still its not working i told thim what i did and to try to upgrade the navigation, but no reply yet.

what shall i do ???:dunno: :dunno:

often just disconnecting the battery will fix this. Upon re-powering the vehicle the i-bus will seek out what devices have been installed and, assuming the bluetooth module has been properly connected, will recognize it and display it as an option on your screen.

thanks for quick respond, but is there a special diagram for the 54 pin (there was a special 54 converter for the BIT II but when i remove he old ulf i removed it).

You might want to check with Martin at bimmernav.com - he likely knows the pin-outs for this conversion harness.

they did what you told me, it shows the telephone on the screen, and on GT1 DIS also it see the bluetooth but pairing is not working.
