I queried Pioneer yesterday at the status of the 2.0 update for the US F500BT. Below is the response I received. Good news!
Thank you for contacting Pioneer Electronics, Inc.It is close to being released, early next week.
In the US we have tighter guidelines for releasing an update.
Everything must be tested and verified that it will do what it says it will do and not cause other problems.
Make sure you have registered your product, registered users will be notified via E-mail.
Thank You,
Rocky
