Hello all!

I just bought a 2011 Elantra GLS on Monday and I have a couple of questions I hope the fine people here could answer for me. Google wasn't much help.

1. My wife's Civic needs a stereo security code entered into it whenever you disconnect the battery. Does my 2011 Elantra need a code? I don't want to disconnect the battery if it does. I don't see any card in the glove box with a number on it.

and

2. I put a few hundred songs on a usb drive and it works, but whenever I turn the car off and then back on, it always goes back to the first song. Is there something I'm missing?

Thanks!
