Check your antenna. If the mast is not extended, your reception will be limited. try an AM station, usually a local AM station will still come in even with the mast down. Have you tried playing a CD (if equipped) ? If that plays well, you've confirmed lack of reception as the problem. If the mast is extended and you still do not have reception, the antenna plug my have come out of the back of the radio. The requires removing the radio to check.
Radio static can be caused by a number of things. The most common are RF interference from a malfunctioning alternator/charging system and a possible bad ignition coil.
I would BEGIN diagnosis by scanning the onboard computer system to see if there are any fault codes in any of the computer modules that may help pinpoint the cause.
two types of noise accur on radio's first is known as a whine,, goes up and down with engine rpm secound is static...normally static is from bad plug wire or plug... you probably have coil packs.. one of them could be arcing.. check it out in the dark of night and look for the spark light. most time good tune up fixes let me know
the cause of this is a defective is due to one of the following:
1. Antenna is defective or Antenna coax lead to radio shield ground
2. Antenna ground is dirty or corroded
3. Poor radio chassis ground.
