1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Leadfan Car Radio for BMW 3 Series E90, E91, E92, and E93 models manufactured between 2005 and 2011. This unit features a 9-inch IPS touch screen, Wireless CarPlay, Android Auto, GPS navigation, Bluetooth 5.1, WiFi connectivity, and supports steering wheel controls and a rear camera.
2. Compatibility and Important Notes
This car radio is designed for specific BMW 3 Series models. Please review the following compatibility information carefully before installation:
- Compatible Models: BMW 3 Series (E90, E91, E92, E93) from 2005 to 2011.
- Audio System Compatibility: If your car has a Harman Kardon fiber optic Logic 7 sound system, or if your factory car plug does not have 8 speaker cables, this unit is not directly compatible. A separate fiber optic decoder box (not included) would be required.
- iDrive System: If your car is equipped with an iDrive system and an LCD display, this car stereo is not compatible.
- AC Control Panel Relocation: Due to the smaller size of the original radio in E90-E93 models, the factory A/C control panel must be moved to the original storage box location. The package includes baffles for this retrofitting.
- Original Buttons: If you wish to retain the original buttons, an ashtray button relocation kit (not included) may be required.
