X350 bluetooth conversion

[andymadmak]

Does anyone know if there is a quick and easy " plug and play conversion kit" to make early x350s bluetooth? I have a 2004 model with the alternate sim phone in the armrest, but most of the latest 4g contracts apparently do not support use of an alternate sim! ( at least according to Orange/EE)

I have googled but the bits on sale seem to require a level of expertise to instal that I am not sure I possess!
