The Connects2 CTKAU01 installation kit provides all components required to install a double DIN aftermarket head unit into Audi A3 (8P) models from 2003 to 2012. The kit includes a fascia panel, CAN-Bus steering wheel control interface, ISO wiring harness, antenna adapter, and radio removal keys to simplify the upgrade and maintain a factory-style finish.

The CAN-Bus interface retains OEM steering wheel control functions where supported and the ISO harness and antenna adapter enable plug and play connections with most leading aftermarket head units including Pioneer, Kenwood, Sony, and Alpine. Professional installation is recommended to ensure correct integration and system compatibility.
