Maybe there is the last line of this tsb says "USB Audio Playback resets after key cycle" which is what I think is happening. When I turn off the vehicle then restart it will play the last song and any songs by that artist. You need to click browse then songs then random to get it to play other songs/artists.
Read my post here from yesterday:

The system DOES remember what you are doing across "key cycles", but there are a few gotchas. When you start the car, the current song playing when you shut if off should resume.
Gotcha: If that song completes before the system has time to index all files on the drive, it goes to a default playback mode. (the details of which are a mystery) After its done indexing, it returns to your chosen random mode.
If the drive is fully indexed before that song completes, it will continue in whatever random mode you were in before.
Assuming you have all files appropriately tagged for artist, album and song title, you have 2 or 3 random modes, which are completely undocumented.
After the drive is indexed, on the audio playback screen where it shows the artwork and tags details, underneath all that it will show 3/15 or the like, where 3 is the track number and 15 is the number of tracks in the album. That should be true in either the artist or album tabs.
Now open the "songs" tab and those numbers should indicate the total number of songs on the drive. Mine will show something like 2378/5619 where the current song is #2378 of 5619 total. So it appears the system actually remembers which of the 3 tabs you were into when you selected "random". But only the songs tab has that unique "random" selection at the top of the complete song list. If you select that, and avoid the above-mentioned gotchas, the system will remain in a true random song mode until you make some change to the drive. Once ANY changes to the drive are made, the system goes back into that mysterious default mode and you have to repeat the above steps.
