I did the Z3 update and it worked great! But the only problem I have so far is it will not recognize my iPhone. I think with the Z2 all you had to do was register it. Now there are different options. Did anyone else get it to work yet? Thanks!

Mine works fine z1>z2>z3...

How did you sync it? I hold the menu button then phone registration I think. Then two separate optinos come up, mobile and nav. I hit mobile and it says like send from phone. Nothing happens...Please help!

Nothing happens because you haven't completed the pairing process. All you've done is told the AVIC that you're going to initiate the pairing from the phone.

To do that, tap Settings -> General -> Bluetooth. You will see the device pop up below the slider to power BT on/off. Tap it and follow the instructions for entering pin to complete pairing.

But it says Paired to the Pioneer in my phone. Should I unpair and repair since it was paired to the old Z2?

Yes
