AK-Motion 3.5 inch Vent-Mounted Touchscreen for BMW 1 Series F20 F21

Add a factory-looking digital dash to your F20 or F21 with the AK-Motion 3.5 inch touch display. The screen sits neatly in the centre air outlet using a model-specific frame, giving you instant access to live telemetry, track timing and diagnostics without cluttering the cabin. Ideal for M140i, M135i and 120i owners who want OEM-style integration with proper motorsport-grade data.

We run this unit on our own M140i and it is brilliant. Customers love how quick it is to read key engine vitals and how clean the install looks. If you want a vent gauge, multifunction digital display or plug-and-play CAN reader for your BMW 1 Series, this is the one we recommend.
