3. Setup and Installation

This Android car radio is designed for a plug-and-play installation in compatible Mercedes-Benz SL R230 models (2001-2007). All necessary accessories for installation, including a dash kit, power cable, RCA cable, reversing camera cable, and USB cables, are provided.

Important Note for Harman-Kardon or Bose Sound Systems:

If your vehicle is equipped with a Harman-Kardon or Bose sound system, an additional 6-meter cable is required for the audio to function correctly. This cable must be purchased separately. Failure to use this cable with these sound systems will result in no audio output.

Cooling Fan Setup:

The unit includes a cooling fan to manage heat during prolonged use, especially in warm climates. Proper setup of the cooling fan is crucial for optimal performance and longevity.

1. Connect: Ensure the cooling fan is properly connected to the head unit.
2. Settings Access: Navigate to the device settings on the head unit.
3. Device Settings: Locate and select 'Device' from the main settings menu.
4. AMP ON: Within the 'Device' settings, ensure the 'AMP ON' option is activated. This step is often necessary for the cooling fan to initiate operation.

It shows how to navigate through the Android settings (Settings > Device > AMP ON) to activate the cooling fan. A comparison of 'High temperature' without a cooling fan versus 'Normal temperature' with a cooling fan is also depicted, highlighting its importance.
