Who it suits

Frequently Asked Questions
Q: Will this stereo fit my car?
A: Most vehicles need a fascia panel, wiring harness and sometimes a steering wheel control interface to fit a new stereo. Contact CEN with your make, model and year and we will confirm the exact installation kit needed, or browse our Connects 2 installation kits.
Q: Will I keep my steering wheel controls?
A: Yes, in almost all cases. A steering wheel control interface retains your existing buttons with the new stereo. Parts are sold separately.
Q: Does this stereo support Apple CarPlay or Android Auto?
A: Check the Specification tab, which lists smartphone connectivity for each model including whether CarPlay and Android Auto are wired or wireless on that unit.
Q: What is the difference between single DIN and double DIN?
A: DIN refers to the chassis size. Single DIN units are the traditional slim format, while double DIN units are twice the height and typically carry a touchscreen. Your vehicle's dash aperture and fascia kit determine which fits.
Q: Can CEN supply and fit the stereo?
A: Yes. CEN offers professional supply and installation from our Nottingham premises, including fascia, wiring and steering control integration. Contact us for a fitted price.
Q: Does the Liberty Motor 4 have DAB radio?
A: Yes. The Motor 4 has a built-in DAB/DAB+ tuner as well as an AM/FM RDS tuner with 30 presets.
Q: Which cars is the RetroSound Liberty designed for?
A: The Liberty radio is designed for vintage Ford, Chevy and GM vehicles with cut or modified dashes, with an ultra-slim profile. Contact CEN with your vehicle details to confirm fitment.
Q: How many USB ports does it have?
A: Two rear-mounted USB ports, both with 2.1A device charging.
