Here's what I don't get though. I was told that the microphone and switch had to be rewired to go to the nav unit instead of the sync module. Yet, that one time I started it up and everything crazy, my voice button and voice control were FULLY FUNCTIONAL. I turned off the car, turned it back on, and the voice button no longer works. My phone works fine, people can hear me so the microphone is obviously working.
The one time I had everything go nuts was when it said "Installing English from Disc" on start-up.
Like I said...
After having everything taken apart for over an hour... I plug everything back in, start the car... My nav system says Installing English from Disc or something like that... Weird, never seen that before. It powers up and voice button on the steering wheel works. I can make calls, control my audio... SWEET! But I go through the nav screen and many things don't work. It's connected with my phone, but it doesn't see my phone on the screen. I cannot place calls using the screen (but can with voice). I can play songs off my USB, but the nav screen does not show the name of the song. Weird as hell.
I turn everything off, disconnect the Sync connectors in the center console and plug them back in, turn it back on, and everything's back to normal. Everything works again except for the steering wheel controls.
