I know this question has been asked (and answered) many times, but after spending some time searching, I haven't found a conclusive answer for my specific car.

I have an '02 X5 4.6is (build date 06/2002) with the widescreen nav head unit and an OEM MKIV nav computer. I've been using a cassette adapter with my iPhone 6 for music, audiobooks, podcasts, etc and while i hated having a loose wire running down the console, it worked.

Yesterday my employer put me on their corporate phone program which included an "upgrade" to an iPhone 7. I would have preferred to have kept my old 6 and received a stipend, but part of the deal is that I had to switch to Verizon and my old phone was on AT&T. One of the "features" of the iPhone 7 is the removal of the headphone jack. So to use it with my cassette adapter, I will also need to use a Lightning-Port-to-headphone adapter. That's a lot of adapters to keep track of!

So, I'm looking for a bluetooth solution that I can permanently connect to the stock audio system and forget about all the wires and adapters. Everything I've seen so far that is compatible with the E53 is for 09/2002 and newer. Does anyone know of a system that can work with what I have?
