I'm after a new headunit for my car, my current one is pretty bad and always has fuzz when listening to the radio.

I have no idea what to look for in these things, I don't know what good brands are and what to get.

Can anyone help me? I want something with clear sound (which most likely will be all of the new ones) aux input and iff possible USB but that is not too important.

I appreciate any and all help. Thanks in advance.
