I just updated the firmware from Pioneer's website. I think I had 2.0 on it previous. After I updated the new firmware, which installed perfectly, I now have the following issues:

 

* System takes about three minutes to boot up

* After three minutes, it then reboots itself

* On this second boot, it only takes about a minute to start

* I lose whatever FM channel I was listening to, and have to go back to the AV source screen and reselect FM

* GPS also seems to get locked up occasionally. I have been able to solve this by changing the screen and going back to the map.

 

Also, these issues were persistent for me in 2.0 and continue with the latest update:

 

* I use a USB key (no iPod right now) and it isn't recognized on bootup, EVER. I have to manually disconnect the USB key from the connector, and reconnect it. Then wait about 30 seconds. And then the key becomes available.
