The users manual says go to Setting{ Setup{ Memory Partition

Only one problem when I do that, the only choices I have are Antenna Aiming, Set Time, Restore Defaults. There is no Memory Partition choice? I've checked all menu choices and have yet to find the memory partition setup.

What is the problem? Do I need a firmware update?

Ok someone told me that it had to be docked or with AC power plugged in, I'd forgotten about that.

My Inno started recording over older content and I knew I was nowhere near 50hrs. I got my Inno a year ago this coming Friday and I could have sworn that I set the partition to all XM when I first set it up, but I guess I didn't. Now I am going to lose everything that I've been recording over the past year, if I reset the memory partition.
I've never used the software CD that came with the Inno, I thought I might be able to save the Inno's contents on my computer and then reload my saved XM recording after resetting the Inno memory. Boy was I wrong what a piece of crap that XM+Napster software is. That was a total waste loading that software on to my computer. Now I am back to sqaure one.
