Dear experts, I'm also looking for latest firmware update. Having currently version 0475 (MIB2 Amundsen in an Octavia III) - see attached picture for details. Background: I tried out a sw update with a wrong source and the update failed. Since that time I get every 10, 15 or sometimes 20 minutes a strange notification sound during driving. I don't know what triggers this and couldn't find any reason. It sounds like a message notification sound and I don't know how to get rid of it. My hope is that an update to latest firmware version could fix this. Or any other idea or proposal? Would be really happy to get rid of this nasty thing... Thanks a lot in advance for any help!
