Honda have released this Audio Visual Navigation Update (AVN) update for the following cars TSB dated 17-04-2103 bulletin number SN-10-008-00. ModelModel Code Year ModelCivic 5DFK1, FK2, FK32012 & 2013CR-VRE5, RE72013CR-V i-DTECRE62013The Symptoms1. AVN screen freezes while listening to iPhone music in Accessory mode. The Navigation touch screen shows only the audio banner with “Stars” in the background and does not respond to touching. Only 3 buttons are operating which are: Seek/Skip, audio volume and On/Off button. 2. Stored voice tags in the navigation system are lost over a period of weeks or if the vehicle is stopped and the ignition is switched Off/On during a route calculation by Navigation unit. The Cause 1. AVN Screen Freeze - A boot up failure occurs when the software gets into an infinite loop after reading correct parameters then incorrectly reading old data that was not cleared from the memory. 2. Lost Voice Tags - If AVN system workload is high, reading of telematic and voice tag information can take too long. If this occurs whilst guidance is in use and ignition is switched off and on, the navigation system judges that voice tag information is incorrect and deletes it. The Fix 1. AVN Screen Freeze - Revised software has been applied to clear old memory locations, so there is no erroneous data that can be read. 2. Lost Voice Tags - Revised software has been applied so that Navigation system does not delete the stored voice tags during route calculation when switching on and off the ignition. Please note you only need to approach the dealer if you have this specific fault.
