Blaupunkt Stockholm 400 DAB
The Stockholm 400 DAB covers all the essentials: a front USB port, rear AUX input and built-in CD player handle your music sources, while DAB+ keeps you on digital radio. Bluetooth 5.0 takes care of hands-free calls and audio streaming, and the analogue steering wheel control input is programmable to suit your car. If you want a similar retro-style unit without a CD drive, the Blaupunkt Madrid 200 BT is a mechless alternative.

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 Blaupunkt Stockholm 400 DAB play CDs?
A: Yes. It has a CD loader for CDDA, CD-R and CD-RW discs, as well as a front USB port and rear AUX input.
Q: Does the Stockholm 400 DAB have DAB radio?
A: Yes. It has a DAB/DAB+ tuner alongside FM/AM with RDS, and the DAB antenna input (SMB) supplies 12V phantom power.
Q: Can I add an amplifier to the Stockholm 400 DAB?
A: Yes. It has 4-channel RCA pre-outs and a 2-channel subwoofer output with adjustable gain and frequency.
