Is this product plug-and-play? Do I need to program or code my Audi? Do I need to buy an external GPS antenna? Can I still check the car info on the OEM screen?
Answer: Yes, it is plug-and-play. It has the same plugs and harness as the original Audi system. You do not need to program your car. All necessary accessories are included in the package. You do not need to buy anything else to make it work. You can still check the original Audi car info as before.

How do I switch the new upgrade system to the original Audi interface?
Answer: Please tap the "Original" icon on the home screen to switch to the original Audi interface.

How do I switch the original Audi interface to the new upgrade system?
Answer: Please tap the screen.

Why does it show a black screen with no signal when tapping "Original" to switch back to the original Audi interface?
Answer: Please check the CAR-LVDS port. Make sure you connect the LVDS plug (removed from the OEM screen) to the new screen.

Why is there no audio from the new upgrade system? 
Answer:
1. Please press the MEDIA button on the radio panel and check the audio source options. Make sure the External Audio input(AUX) is activated.

Note that if your car has the AMI option instead of AUX, you need to plug the Audi AMI-AUX cord(this cord is sold separately) into the AMI port in the glove box on the passenger side. After plugging this cord, the AMI will change to AUX on the screen

2. Then tap the screen to access the new upgrade system. You should be able to hear sound.

Where should I mount the main metal box? Is the original LVDS cord too short to mount in the glove box?

Please take apart the glove box on the passenger side; there is a hole that allows you to hide the metal box behind the screen. Then the LVDS cord is long enough.

Why does it not power off when I shut down the car?
Answer: Please ensure the CANBUS connector is connected behind the climate control panel, as shown below.
