Bluetooth and smartphone connectivity
Bluetooth lets you make hands-free calls and stream music wirelessly, with two phones connected at the same time. Pioneer's Advanced Sound Retriever technology helps maintain audio quality over Bluetooth. Connect your iPhone or Android device and use Spotify (Free or Premium) or the Pioneer Smart Sync app directly from the head unit.
Audio performance
The MVH-S520BT reads FLAC files via USB and offers serious sound-shaping tools: a 13-band graphic EQ, time alignment, 3-way network mode, and three RCA pre-outs for connecting external amplifiers or a subwoofer. The onboard MOSFET 50W x 4 amplifier handles day-to-day listening, while the pre-outs give you room to expand. A Karaoke function is also included.
If you'd prefer DAB digital radio alongside these features, the Pioneer MVH-330DAB is a comparable mechless single-DIN option with DAB built in.

About the Pioneer MVH-S520BT
From our tech experts at CEN
The Pioneer MVH-S520BT is a single-DIN mechless car stereo with Bluetooth for hands-free calling and music streaming from two phones at once. It supports Spotify and the Pioneer Smart Sync app on iPhone and Android, with USB and a front Aux-in for wired sources. A MOSFET 50W x 4 amplifier and three RCA pre-outs make it a solid base for a larger system.
Who it suits
It suits drivers who want wireless connectivity without a CD drive, keeping the dashboard tidy and the chassis compact. The three RCA pre-outs appeal to anyone planning to add an external amplifier or subwoofer. For DAB digital radio as well, the Pioneer MVH-S420DAB is a comparable mechless option.
Our tech experts advise
The short-chassis design fits most single-DIN spaces, but check your vehicle's depth clearance before ordering. The unit reads FLAC files via USB, and the 13-band EQ and time alignment give precise control once fitted. Installation is priced per vehicle — see our car audio installation page for a Nottingham fitting quote.

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: Can I connect two phones to the Pioneer MVH-S520BT?
A: Yes. Bluetooth supports two phones with full-time connection, so both can be used for hands-free calling and music streaming without re-pairing.
Q: How many pre-outs does the MVH-S520BT have?
A: It has three RCA pre-outs (front, rear and subwoofer). Combined with 3-way network mode, time alignment and high and low pass filters, it can run external amplifiers for a full component and subwoofer system.
Q: Does the MVH-S520BT have a CD player?
A: No. It is a mechless (Mechafree) receiver. Music plays from USB (MP3, WMA, WAV, FLAC and AAC files), Bluetooth streaming, Spotify via your phone, or other devices through the front Aux-in.
