This sounds like a good idea, but can anybody explain how to do it? I have the same issue with my AVH-2600BT. I have gotten some of the 800x480 backgrounds on this site to look OK when I view them in "Zoom" mode, other than small gaps on the side, but when I download them the quality degrades considerably and has artifacts. I've tried other aspect ratios as described here. Everything looks poor when I use it as a background. Frankly, I'm not sure why Pioneer bothered to offer this feature if they can't get it right. It's not like displaying something in full resolution is rocket science. Any other suggestions would be appreciated.
