I have an iphone 4 and Pioneer x920bt.

My iphone is paired to the headunit

I downloaded the avic app, mapped a route, but it didnt transfer.

Can someone explain the steps to using this feature?

Re-upload the BT contacts to the unit. You can do it from the CONTACTS menu.

Then why does NavGATE icon shows in the menu ??

Why is that? Why does it use contacts? That is kinda weird.

That icon has nothing to do with the phone. Its for the PC app.
