On July 25th, the latest TSB that is supposed to solve all of the head unit issues was released and is now available for an upgrade at your local dealer. Reference TSB 15-211-17r. It will install software version U0.18.22.20 on all HK head units so make your appointment and get-r-done!

I thought something looked different when I adjusted the volume today. Just had my car at the dealer for a few issues and they completed the update.
