Our unit was sent in for warranty repair to Pioneer couple of months ago. It came back indicating it needed a firmware upgrade. When I look at the verison it is 1.000000.

Looking at their link for upgrading at :

http://www.pioneerelectronics.com/pna/v ... 48,00.html

It seems they didn't do anything on warranty.

Has anyone performed the firmware upgrade on their own, by downloading from the Pioneer website??

Yes, many people have done it. Works great

Everytime I try to do this upgrade, it doesnt work.

"unable to record cd" wtf?

its single session I think, and its mode 1 for sure, only files on the CD-r

how do you guys burn this? data right?

bump for answer

talk about a dead topic, ill make a thread soon I guess.
