Hey guys, at the risk of bumping an old thread, I thought you'd all be happy to know Pioneer did, in fact, release a new version of the firmware for BT AVRCP 2 days ago. I haven't updated my stereo yet, but because I use an Android phone (no track display on the unit) I am also interested to see what this will do for me. Here is the link at Pioneer's website:
ETA, sorry I'm too new..can't post a URL..just search for this radio model # at Pioneer and you'll see the link for the firmrware update there.
PS My stereo currently says firmware version is: HW04-SW01.07.23
The new update from Pioneer is: HW05-SW01.27.20
