ULF or MULF
 

Hi all. I am planning to get the bluetooth kit. First of all I will be getting the ULF to start with. I found a guy who sells the ULF off ebay. But it says that it is MULF not the ULF. Is there any difference between MULF and ULF. I am attaching the pics.

Also on the pics I couldnt find the passkey. Do you guys think this will work? Thank you.

Yes, there is a big difference. The MULF module is for the MOST based cars (all the new body style cars, like E60 5 Series, E65/66 7 Series, E63 6 Series, and E90 3 Series). The MULF will not work in the E38, E39, E46, Z4, X3, and X5.
