The Limcet P306 is a popular MMI (Multimedia Interface) integration box used primarily in Mercedes-Benz and BMW vehicles to add wireless Apple CarPlay and Android Auto to factory infotainment systems like NTG 4.5, 4.7, or 5.0. 1. Connection & Setup Guide To get the system running for the first time:
Enable Bluetooth & Wi-Fi: On your smartphone, ensure both Bluetooth and Wi-Fi are turned on [11].
Pairing: Search for the Limcet box in your phone's Bluetooth menu (often named "Limcet-XXXX" or similar). Once paired via Bluetooth, the box will negotiate a 5GHz Wi-Fi connection to stream the CarPlay/Android Auto interface [17, 18]. The Limcet P306 (often referred to as the
Permissions: Accept the prompt on your phone to "Use CarPlay" or "Enable Android Auto" [18].
Switching Interfaces: Most units require you to hold a physical button on your car's console—usually the "Back" or "Menu" button—for 3 seconds to switch from the OEM screen to the Limcet menu [2]. 2. Audio Troubleshooting
A common issue with Limcet units is "no sound" because the audio must be routed correctly through the car's native system:
AUX/AMI Selection: Ensure your car's factory radio source is set to AUX or AMI. If your Mercedes does not have an AUX option, you may need a "USB-to-AUX" adapter or an AMI cable provided with the kit [1].
Bluetooth Routing: Some newer Limcet versions (for NTG 5.0+) use a "BT Transmitter" mode. You must disable "Use Car's Bluetooth" in the Limcet settings and instead pair the box's transmitter directly to the car's OEM Bluetooth telephone menu [1]. 3. Key Feature Support
Steering Wheel Controls: The P306 typically supports factory steering wheel buttons for volume and track skipping.
Camera Integration: It supports both factory rearview cameras and aftermarket 360-degree cameras [3].
Screen Mirroring: In addition to CarPlay, the unit often includes "Mlink" or similar apps for direct mobile screen mirroring [3]. 4. Advanced Settings (DIP Switches)
If your screen is black or the resolution looks distorted, you likely need to adjust the DIP switches on the side of the box. These physical switches tell the box which car model and screen size (e.g., 5.8", 7", or 8.4") it is connected to. Consult the diagram printed on your specific unit for the correct toggle positions [2].
