If I totatly screw up my Rio Car, can I just reinstall the 1.03 image useing the wizard?

That's exactly right.

The upgrade wizard re-flashes the kernel and rewrites the boot/player/software partition from scratch.

And the software that listens for the upgrade signal is in ROM, and it's the first thing the player does when power is applied. So no matter what you do to the hard disk, you can at least start over with an upgrade.

Very clever, the way they made it idiot-proof like that.
