We have to remember that in this forum we are living in a bubble. The majority of us are buying pure appradio products. We either have the AppRadio 1,2 or 3. However currently Pioneer has dozens of appradio compatible products, and recently launched a whole slew of updates to any radio that could handle it to upgrade its firmware to support the iPhone 5. They aren't even done with that yet, because the update broke pandora for many of these radios. Pioneer has promised on their facebook page to make repairing that issue a top priority. I guarantee you that we will not see any update to appradio 2 before this fix is implemented on these radios.
My hope is that after the pandora issue is resolved, they will give the appradio 2 an update to enable the parrot bluetooth hardware to use its stereo bluetooth capability and to give us siri eyes free. Hopefully anyways.
