Is this product plug-and-play? Do I need to program or code my Mercedes-Benz? Do I need to buy an external GPS antenna? Can I still check the original car info on the OEM screen?
Yes, it is plug-and-play; it has the same plugs and harness as the original Mercedes-Benz system, no need to cut wires when installed. You do not need to program/code your car when installing. 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 Mercedes-Benz car info as before.

Can I operate the original Mercedes-Benz interface via a touchscreen?
No. You can only operate the original Mercedes-Benz interface via the command knob.

Can I operate the new navigation system interface via the command knob?
Yes. You can operate the new navigation system interface via the command knob.

How do I switch between the new Navigation system interface and the original Mercedes-Benz interface?
Please press the "BACK" or "CLR(C)" command button for 3 seconds to switch between the original Mercedes-Benz interface and the new navigation system.

Why does it show "No signal" or a blank screen when switching to the original Mercedes-Benz interface?
Please check the LVDS port. Then, connect the LVDS plug (removed from the original Mercedes-Benz screen, not the end from the original head unit) to the "CAR-LVDS" port on the control box.

Different audio systems(Audio 20/Audio 50/NTG 4 and NTG 4.5) have different LVDS plugs.

Why is there no audio from the new upgrade system? 
1. Please check if your car has an AMIAMI or USB port. Usually, it is in the center armrest box or glove box on the passenger side.

2. If it is an AUX IN port on your car, please activate AUX mode, then switch to the upgrade system to get sound.
If it is an AMI port on your car, you need to buy our AMI-AUX cord and plug in the AMI port. Then you will see the AUX audio option, activate AUX mode, then switch to the upgrade system to get sound.

Why does the Sirius/XM radio, CD, original car computer info, and factory camera not display?
Please check the fiber optics plug. You need to move it from the original connector to the new connector we provided.
