I have all my music on a USB drive and periodically I get a message to "Please Update the GraceNote DB". After some googling it looks like I should go to the Toyota and look up Updates. There seems to be a way to update the Infotainment System (including GraceNote) by connecting a blank thumb drive, downloading the current system to it and uploading that to Toyota (I may have mis-stated the exact process). When I do that, I'm told that my system is up to date. Supposedly that should have done the GraceNote update, too. What does GraceNote do for me? Just get better album cover shots? I still can't figure out how to switch to various play modes. It usually never leaves the current album, sometimes just repeating the same track over & over. Sometimes just randomly tapping the Next Track and that little icon to its right, I can switch to a different album, but no definable process. Previous vehicle gave me options like random tracks in current album, random tracks in random albums, sequential play, etc. This seems to be lacking on the Prius. Clicking Source and starting over is pretty kludgy. Does Toyota ever do Over The Air updates to this car? TIA Don Central VA
