I need to buy a bluetooth module for my 2008 focus as I suspect my one is faulty but I'm not sure if the one I've seen second hand will work in my car. According to the seller it was taken from a 2011 fiesta (PART NUMBER IS 8M5T-19C112-AT) but it will fit my 2008 focus apparently??? Is that true??? I thought it wasn't as easy as that.
Also is there a test I can do on my old module to be sure it's finished?
