Put the image on a thumb drive or a SD card and plug it into ur AVIC, then go into the settings and change it. Refer to your owner's manual if you can't figure it out.
i Just installed a Avic-f900bt in my 2008 Xterra, and now im in need of a splash screen! It's Red Brawn in color. So something with the color of the car would be awesome. If anyone has any Ideas feel free to throw them at me! Thanks a ton!
