Do I have a bad ULF?

I retrofitted Bluetooth into my 03' X5 back in 07' using the latest ULF 84109154358. It worked flawlessly for every phone I paired to it until recently. I tried pairing my iPhone 6 to it and all I get is "activate phone". I had my dealer clear the ULF as I more than likely hit the 4 phone max on the ULF, but I still cannot pair my 6 phone.

I Press the pairing button in my center armrest for 3 secs, turn the key the position 1, hold for another 5 secs, and release. Still no pairing.
