About the Connects 2 CTKAU01
From our tech experts at CEN

It includes a double DIN fascia, CAN-Bus steering wheel control interface with ISO and Quadlock looms, two aerial adapters, release keys and a universal patch lead.

Who it suits
This kit suits Audi A3 8P owners from 2003 to 2012 who want to fit an aftermarket double DIN head unit while keeping their steering wheel controls. It is not compatible with models fitted with a digital amplifier. If your A3 has a single DIN aperture, consider the Connects 2 CTKAU10 single DIN kit instead.
Our tech experts advise
Your replacement head unit must have RCA audio out connectors for the steering control interface to work. Date and time will not be retained after fitting a new stereo. This kit is designed for industry-standard units from brands including Alpine, JVC, Kenwood, Pioneer and Sony. Fitting is priced per vehicle — contact us to book installation.

Frequently Asked Questions
Q: Is this installation kit right for my vehicle?
A: Installation kits are vehicle-specific. Check the compatible makes, models and years in the product description, or contact CEN with your registration and we will confirm the exact kit you need.
Q: What is included in a stereo installation kit?
A: A typical kit includes the fascia panel to fill your dash aperture and the wiring harness to connect the new stereo without cutting factory wiring. Some vehicles also need an aerial adapter or steering wheel control interface, listed separately.
Q: Will I lose my steering wheel controls when fitting a new stereo?
A: Not if you use the right interface. Where your vehicle needs one, a steering wheel control adapter retains your existing buttons with the new stereo. We will advise if your vehicle requires it.
Q: Which Audi does the CTKAU01 fit?
A: The Audi A3 8P, 2003-2012, with a non-amplified, half amplified or BOSE amplified system. It is not compatible with models fitted with a digital amplifier.
