Whats the largest chip will the X920 support?

32GB probably.

I tried a 32gb card formated in exFat and my 920 said can't read card.

I thought using a card would be the cats meow, But I was wrong, I find using my itouch for music and movies is a lot better.

thats because with a SD card you have to have a good folder structure to be able to find any thing, where as with an Ipod every thing is filed away by the MP3 tags, and there is a built in search feature to find the music you want to in many different ways, the Ipods are much superior to flash memory, hell i think that they sound better as well.
