I haven't resolved everything, but after an e-mail from Pioneer CS today, I've had a mini "break through" tonight with the SD card. They said if you only have jpeg images on the card, that it would not be recognized on the main screen or put an icon on the left side for you.
Some may already know this, but if you want to put on your own splash screen, you have to go to the main home screen (with the 3 large icons). At the bottom right corner is the settings button we all like to play with. Press that and go to "System Settings". In here press "Flash Screen". In there, you can select from the default ones or, at the bottom right corner you can "select from SD". I pressed the SD select button. Then it told me "No jpeg files are in /Pictures/ folder. Add jpeg image to folder.
So I took it out and looked at it on the computer again. I had no folder called pictures on the card. My Verizon phone had, by default, been saving all of my pics to a folder called "mypix". On the SD card, I simply created a new folder called "pictures" and moved one jpeg from my camera phone to it and one jpeg from my regular digital camera to it. Went back to the Avic and tried it again. No soft key on the left side obviously, but when I went back through the steps listed above, sure enough. Both pics' links showed up on the screen and were available to use for the splash screen. I selected each of them and both came up available to use. Very happy right now.
Hope this helps somebody out there.
