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.
