OK. So far so good, but I've just hit a snag.

I'm now at the point where I've reinstalled AND rebooted (as the manual suggests). The player is unplugged power-wise.

I ran the upgrade app and picked 2.0b3. It confirms I want to use the serial port. I'm also warned that power should not be applied to the unit (it isn't). And thennnnn ...

I get Error "Car player not found" occurred during stage 0x00.

Wouldn't I at least need to apply power for it to check with the unit and see that its there? Or does it not normally need any power at this point? Instructions suggest it doesn't, unless I'm misreading.
