I have a 4th gen in my car, but honestly a USB stick has better integration with my 2013 Toyota stereo so I don't use it anymore.
My old car didn't have USB or AUX so I had the iPod and a cassette adapter.Jeeze I've had that thing a long time.
I was very disappointed with Toyota's iPod implementation. It's so time consuming to find tracks. Unless you just want to shuffle. It'll shuffle all day long, but finding songs is a PITA...
Oh, I could use a playlist, but they are a PITA to create.
