Have you tried re-applying v1.03 and seeing if it's better?

My suspicion is that maybe the boot logo you uploaded was too large, and ran into the "c000" area of flash, which contains the "watchdog powerup" code - this gets run if the power control pic wants to wake up the system when the car is off. This is an as-yet unused feature to allow things like contacting your car via wireless even when the empeg is off. The default code here just does a permanent shutdown, ensuring the unit won't wake up again.

If this got corrupted/erased, then the system would probably do a full powerup as if you'd turned the ignition on - except, the unit should have then shutdown (as the ignition line is low). Does the unit know it's in the car (ie, does the fader option appear in the sound menu?)

Obviously, the logo uploader shouldn't do this, but it may have a bug.

Try re-installing v1.03 (this won't remove your logos) and let me know your results.
