Will a iPod nano 7th generation work on a 2012 rav 4?
Should work just fine since it has Bluetooth 4.0 built in. So, if your RAV4 has Bluetooth as well, just pair the 2. Even if it doesn't, you should be able to use the Aux Jack or USB Cable to play the music (I'm sure the RAV4 has one or the other).
