The screen for the navigation and audio system in your is more than likely a "Thin Film Transistor Liquid Crystal Display" (TFT LCD), which is very similar to the screen in a laptop computer. It not only uses advanced micro-technology to operate, it's also coated to minimize glare and remain sharp and vivid almost all the time.

Here's the right way to clean your touch screen in your car:

1. Make sure the screen in your car is turned off - you don't want to interfere with any pixels while they're still firing. Turning off the screen will also allow you to see dirt, dust, and grime better because you're working with a dark surface.
2. Find your microfiber cloth. These soft, dry cloths are the same type of cloth you would use to clean your smartphone, eyeglasses or tablet. They're perfect for the LCD screens in cars because they’re non abrasive. A high quality microfiber cloth will work efficiently when dry to clean most screen dirt and dust.
3. What not to do: You don’t want to use paper towels or old cotton rags because these can scratch your screen. These materials are both highly abrasive, and neither will be particularly good at lifting dirt from the screen’s surface. If you use one of these, your monitor will still be kind of dirty, and you run the risk of scratching or leaving behind lint particles.
4. Gently wipe the screen with the microfiber cloth from top to bottom using a circular motion. Try not to press too hard as this can damage your LCD screen. Continue to use the microfiber cloth to remove any remaining smudgy oils.
5. If you have a lot of dirt or any other tough sort of build up on your device, then you’ll probably need to use something more than a dry cloth. Spray your microfiber with a small amount of ammonia and alcohol free screen cleaning solution. Ordinary household window or kitchen cleaners, should never be used, as the alcohol or ammonia in the cleaner will damage the screen.

 
Some extra tips:

• Avoid getting moisture in any ports on the car’s dashboard and don’t let the cleaning solution sit on the multimedia or satellite navigation screen for too long.
• Using an alcohol-based cleaner on your device will damage the protective coating on most screens in cars.
• Do not wipe or clean your touch screen with paper towels or facial tissues, as these can scratch the surface. Using a microfiber cloth is the only safe way to clean your touch screen.
