Replaced my totaled 2010 III with JBL upgrade with a 2013 II. I could not justify paying up an extra two grand for their suped up OEM stereo in the 2013 III and you now have to go to a IV to get the JBL stereo. I figure even if I dont spend a fortune I should be able to get a better stereo for alot less. Any suggestions or special warnings? We want satellitee radio,cd,bluetooth and still be able to use controls on wheel.
