The anti-theft protection feature disabled the radio when it is disconnected from the battery, which includes the battery losing power.
When you purchased your vehicle, it came with a card that lists your radio code on it. If you can find the card things will be easier for you.
Now we can start trying in this way:
You simply turn your ignition and radio on and press and hold the power volume knob for two seconds. The stereo system will recognize that it is in your vehicle and you will regain access to the radio.
If it does not work, this feature may be absent and you will need the code. Turn the ignition switch to accessory and turn the radio on. If the display does not say CODE, disconnect your battery for a few minutes and try switching everything on again. the word CODE should be flashing and you simply enter your five digit number in the car i said the code should be.
we have 3 options to retrieve the code.
• The 1st way to retrieve the radio code is to look in your glove box or owners manual. The code is on a sticker usually stuck or placed on the inside of the glove box.
