I think that when one does a retro fit using bmw oem bt kit.... (bought my car new without getting the option of BT at the time plus VR is another option price goes up) the ulf is not coded and will work with any specific car... and VR worked fine without coding... mine was only coded after retro fit of sat nav + tv hybrid.... i even told the tech that my BT was VR enabled.. and showed him it working... when the coding was done... SA620 and SA644 was on the data sheets for my car specific, for Euro cars it is definetly the case of pay more for your options... or disable them at factory ....

It was 3rd gen ulf 'ulf mit ses'

And i have VR for the sat nav not all but most and the scale is in metres
when my map screen is in yards... lol but it works and i am happy...
