One mistake I made on my 2010, was that I never hooked up the wires for a "powered antenna". I thought, "pffft, I don't have a power antenna!" But our antennas are powered. I'm not sure if that's for all years, but for like a year I thought it was just my JVC was lousy at picking up stations, especially AM. Until I read some random comment on the internet about a Golf or Jetta having a powered antenna, and the difficulty pulling in stations if you don't hook it up. This may not apply to you, but I'd hate to see you go through the trouble if that's all it was.
