The only reset is to disconnect power to the changer at the fuse box for 30 seconds. I doubt that will help, you likely just have a defective player.

P0300 75 Random/Multiple Cylinder Misfire Detected

What does that mean?

Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 OBD code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer
Possible Solutions

If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e.spark plugs ). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Check your fuel pressure at idle and when at higher rpm while not driving. You can usually borrow a pressure tester from an auto supply store. The place to test it will be on the fuel injection rail on top of the intake manifold. I would buy a Haines manual too.

YOu have a blown fuse. The OEM radio has an error code and basic power supply that gives you an error response. Check your fuses and make sure that the main fuses and fuses for the radio and console unit are good. If it's an aftermarket unit it may be a bad cmos battery that needs to be replaced.

Just needs a 4 wheel alignment. Probably needs a few suspension parts as well. A good Indy shop is the place to go.
