Ray Kawel has a great writeup on his web site explaining exactly what wire to tap into and what pin position to push it into on the radio connector . He also sells the wire with the correct pins which made installation a snap

I did the same conversion then banged my head against the wall when I could not get the navigation to work
I found Ray's posts , sent him a few emails , installed the wire and bingo, the nav worked great

Let me know if you need the web address

So all good! Tested it on the way home today and it did interface with the HUD. I should have done this swap a long time ago!

Do you have it set to "Street" mode , the nav will not display in any other mode

One question - can you answer/disconnect phone calls using your steering wheel controls?

Not sure yet about any future pairing issues, but I do still have BT functionality in the car.

Hopefully you won't get a new phone or have to reset either the phone or the cars BT anytime soon.

Both units are security-mated to the car so I would think there would be no issue, but for the hour or so to get it done.

Thoughts?
