The factory radio amp in a 1999 Jeep Cherokee Laredo provides extra power to the radio unit to drive the speakers at higher volume levels. In addition to powering the speakers at high volume levels, the amp makes the sound clearer at all volume levels. Occasionally, the amp can draw too much power, causing its integrated reset switch to trip. This switch is designed to prevent the amp from overheating and causing a fire or damaging its internal components. When this switch trips, it needs to be reset directly on the amp itself; there is no external or dash-mounted reset switch.

Fold the rear seat back down so the seat cushion locks into place. Test the radio to make sure that it functions properly.

The Volkswagen New Beetle, like many other vehicles made in recent years, is equipped with a radio that requires a code to properly function after being disconnected from its power source. This feature is designed to make the radio as useful as a paperweight in the event of theft. The need for a radio code has served to reduce the theft of original equipment manufacturer (OEM) radios, but it also makes it annoying for owners who have removed their radios for various reasons, including replacement and service.

Look for the Vehicle Identification Number (VIN) of the New Beetle if the VW owners manual does not contain the radio code. You can find the VIN near the bottom of the windshield on the drivers side of the vehicle. Write this information down on a piece of paper.

Remove the radio from the dashboard. You will need a set of radio removal keys, available for purchase at most car audio outlets. Insert the radio removal keys firmly into the two slots along the bottom edge of the radio then pull the radio out of the slot. Look for the radio serial number located on the back of the unit. This number will start with "vw4z7" or a similar identifier. Write this serial number down on the same piece of paper as the VIN for safekeeping.

Take the information written down to the nearest VW dealership and request that they find your radio code with the information provided. Both the VIN and radio serial number are required for the dealership to successfully find your radio code. Upon finding the radio code, write it down in the owners manual or someplace else where you can safely store it.

Audi created the radio in a 1998 A4 with security in mind. The radio has a built in anti-theft system that locks out the radio functions whenever it loses battery power. This loss of power could be caused by a disconnected battery, faulty battery or simply a battery with a low charge. Regardless of the reason for loss of power, a security code is required to restore the radio to its normal operating condition. If youve lost your radio code, youll need to gather some information and visit your local Audi dealership in order to obtain a new radio code.

As a theft deterrent system, Mitsubishi programs its car radios with a 4-digit code that locks the audio system when tampered with. Trouble is that sometimes the system locks up even on legitimate owners, leaving them without the ability to play compact discs or use the radio.



If you see a prompt that reads "Code," dont sweat it, the user manual should contain a reset code. If no manual is available, Mitsubishi hosts a website which will send you the code as long as you have your vehicles VIN and the radios model and serial numbers.
