I have a 400NEX and I finally figured out how to get AppRadio working via BT and an MHL cable. However, when I went through the initial setup I didn't understand the interface and didn't adjust the screen borders correctly, and now have major overscan on my screen. How can re-run the setup wizard to calibrate the screen correctly? I tried clearing the NEX's Bluetooth memory and re-pairing to see if that would set it up as a new device but that didn't help.

Thanks in advance.

I reached out to Pioneer support and apparently I need to perform a full factory reset in order to re-run the setup.
