What does COD mean on the audio display screen?

If the touch screen on your 2005 Jaguar X-Type is blank and you are receiving codes 50 and 51, it indicates that there is a communication error between the audio control module and the touch screen display.
Here are a few things you can check:

1. Wiring and connections: Check the wiring and connections leading to the touch screen display and the audio control module to make sure they are in good condition and properly connected. A loose or damaged wire can prevent the display from working correctly.
2. Audio control module: The audio control module is responsible for sending information to the touch screen display. If the module is malfunctioning or damaged, it can prevent the display from working properly. Check the module for any signs of damage or wear, and replace it if necessary.
3. Touch screen display: If the display itself is malfunctioning, it may need to be replaced. Check the display for any signs of damage or wear, and replace it if necessary.
4. Software update: There may be a software update available for the audio control module that can fix the communication issue. Check with a Jaguar dealership to see if there are any updates available for your vehicle.

Mine did this after kids played with it, just hold the power/volume button pressed down for a few seconds and it will go back to normal.

Have you checked all your fuses? Display and memory may be on separate fuse.

stereo codes for Honda

Method 1 (all applicable models except '03-07 Accords with the navigation system)
1. Turn the ignition switch to ON (II).
2. Turn on the audio unit, and make sure you see stereo COdE in the display. If you don't see this message, pull the backup fuse for 1 minute, and then go back to step 1.
3. Turn off the audio unit.
4. Press and hold the 1 and 6 preset buttons, then turn on the audio unit. The display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200). The second screen displays an L and the last four digits of the serial number (for example, L0055). Ignore the U and L, and write down all eight digits.

Method 2 ('03-07 Accords with the navigation system)
1. Turn the ignition switch to ACC (I).
2. Turn on the audio unit, and make sure you see COdE in the upper display. If you don't see this message, pull the backup fuse for 1 minute, and then go back to step 1.
3. Turn off the audio unit.
4. Press and hold the top halves of the SEEK/SKIP and CH/DISC bars, and then press and release the PWR/VOL knob. This display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200). The second screen displays an L and the last four digits of the serial number (for example, L0055). Ignore the U and L, and write down all eight digits.
5. Call Honda Dealer for Radio Code.
6. Use the TUNE knob to enter the first four digits of the anti-theft code into the audio unit. (Ignore the last digit; it's not used.) When you turn the TUNE knob, COdE disappears, and a single digit is displayed. Turn the knob left or right to select each of the anti-theft code digits. When you press the TUNE knob, the system beeps and accepts each digit as it spells out CODE on the display.

Hope this help.

This is a security feature. COD means Code. same thing happend to me on my volvo, i called the local dealership and they asked me for the vin and looked it up. hope it helps

Yes, it means you need to put the code in for the radio. If you call the dealer they may be able to get it for you or http://www.radio-code.com/

I think you can modify the setup setting to just show the screen you want and don't come back to Nav screen
