Android Head Unit for BMW 3 Series F30/F31, M3 F80 (2011–2021): Complete Selection and Installation Guide

BMW 3 Series models in F30 (Sedan), F31 (Touring), F34 (Gran Turismo), and the performance M3 F80 versions have earned iconic status thanks to their handling and design. However, their factory infotainment systems (CIC, NBT, NBT EVO), which felt cutting-edge in 2013, now lag significantly behind modern smartphones: slow navigation, costly map updates, lack of wireless Apple CarPlay / Android Auto, and no support for video streaming (YouTube, Netflix).

Installing a modern SMARTY Trend Android Head Unit is the best solution to upgrade your BMW F30/F31/F80 interior while retaining all factory functions.

If you've already read our article on upgrading the BMW 5 Series (E60, F10, G30), the working principles of NBT and NBT EVO are explained there in detail. Here we cover specifics unique to the 3 Series.

1. Identifying Your Factory BMW System (CIC, NBT, NBT EVO, S663)

The key step before purchasing an Android screen is correctly identifying the generation of your original iDrive system. This determines the LVDS video connector type that plugs into the head unit.

2. SMARTY Trend Product Line for BMW F30 / F31 / M3 F80

The catalog offers several form factors of multimedia systems and additional hardware:

• Processor Platform: Octa-Core Qualcomm Snapdragon chipsets (up to 8 GB RAM / 256 GB ROM).
• BMW System Retention: iDrive controller, steering wheel controls, parking sensors, factory camera, and trip computer work seamlessly.
• Wireless Connectivity: CarPlay and Android Auto are active out of the box in all series (10.25", 12.3"). Options available for LHD (Left-Hand Drive) and RHD (Right-Hand Drive).

3. Step-by-Step Installation Guide

Installation is completely Plug-and-Play without cutting factory wires. You will need plastic pry tools, Torx T20 screwdrivers, and a Phillips screwdriver. Time required: 30–60 minutes.

1. Disconnect the Battery:
   Mandatory step before handling car electronics to prevent CAN-bus fault codes.
2. Dismantle the Center Console:
   Use plastic pry tools to unclip the central air vent panel containing the hazard light button. Remove the climate control panel and unscrew the original NBT/EVO screen mounting screws.
3. Connect Main Quadlock Harness:
   Unplug the factory harness from the head unit and connect it to the SMARTY Trend adapter harness.
4. CRITICAL STEP – Optical Cables (MOST):
   Warning! If the original Quadlock connector includes two green (or green-black) optical fiber cables for the MOST bus, gently transfer them from the original connector to the corresponding slot on the new adapter harness! Skipping this step results in no audio and disables factory amplifiers / Harman Kardon systems.

1. Install CANBUS Decoder & Antennas:
   Place the provided CANBUS module behind the head unit. Route the GPS and 4G antennas under the windshield (top dash area), away from metal shielding.
2. Reassembly & Testing:
   Mount the new SMARTY Trend screen, secure the screws, reconnect the battery terminal, and test iDrive knob functionality, climate controls, steering wheel buttons, and backup camera.

Note: If you are installing an optional 8.8" Touch Climate Panel, it hooks up via an inline pass-through adapter directly to the factory climate harness.
