BMW E30 Ashtray Modular Conversion System – USB, Volt Meter, Switches, and Mounts

Please note: the conversion base plate is a mandatory purchase; the modules will not fit on their own.

Overview

Upgrade your BMW E30 interior with our modular ashtray conversion system. This retrofit replaces the factory ashtray with a multi-functional mounting panel designed to accept various modules—USB chargers, volt meters, I/O switches, or universal ball mounts. Perfect for enthusiasts who want to modernize their E30 without compromising the OEM look.

Each module uses E36-compatible dimensions, making it possible to integrate E36 OEM switches. All modules come pre-wired with a 2-pin connector for quick and clean installation to any 12V power source.
