No I took it back to 2.0 then the 1st (2.1) then the 2nd (3.0xxx). 2.06 was the update to fix the DST. I used this topic to get back to 2.0 http://avic411.com/forum/viewtopic.php?f=33&t=25424
I just got done with the 3.0 again and this time it worked. I don't know why but all I did was go back to 2.0 and start the upgrade I did not do 2.06. so maybe that was it this time.
I am having the same issue. I called Pioneer and they want me to send the unit back. I am going to reset it back to 2.0 and check it then try to update it again.
