How to 'play all' from iPod?

OK, so we just got a 2012 Prius and I was psyched on the ipod integration and loaded up 60GB on an old iPod and stuck it in the car and had about 4 hours of total random shuffle bliss. Then I wanted to show it off to a friend and I used voice command to tell it to play a song, which it did. But now it will only play that song. It seems it now has a playlist of only that one song and there's no way to disable that. The best thing I can do is say "play songs like this" which chooses 25/50/100 similar songs, which I don't want. if I use the back arrow the only top level options I have are artist/album/song/genre and selecting any of those requires me to make another selection, even "all songs" just takes me to a list of all the songs, no way to select play all the songs. If I click a song, then it just plays that one song, repeatedly (and no, repeat isn't selected)

I want to play ALL the songs on random again, but can't seem to find anyway to do that. Does anyone have any insight into this problem? I RTFM and it's useless.

thanks.

 

Thanks! I do have the HDD Nav version - But this is the weird thing - I have no options to play a playlist ever. I have playlists on my iPod, but I don't have an option to use them when it's connected. Artist, Song, Album & Genre only. No playlists anywhere.... :\

 

Interesting. This is an old iPod, though I don't recall anything different with my iPhone, but I'll have to check and will try making a new playlist like you mentioned. Thanks!
