Bluetooth® for your car

Bluetooth adds a whole level of wireless convenience to my drive — like hands-free calling and easy wireless access to the media on my smartphone. And since I'm an IOS guy, I love how the AVH-521EX supports Siri Eyes Free when I'm in the car. Touch a button and I can listen to and send text messages, place calls, and ask questions, all without taking my eyes off the road.

Your A/V on tap

This receiver covers the bases with CD and DVD playback, an aux input, plus Android™ and iPhone® control via USB. Your inner audiophile will love the FLAC file support for true high-resolution music — up to 192kHz/24 bit. You can get a video fix by watching DVDs when the parking brake is engaged or send the video output to optional rear-seat screens to entertain your passengers on those long road trips. Add a rear-view camera and you'll get a better view in crowded parking lots or backing out of your garage. With select rear-view cameras, you'll even get parking guide lines that curve with the motion of your steering wheel.

Stellar sound quality you'll love

The AVH-521EX rocks out with a powerful amplifier, supported by a versatile 13-band equalizer that tames the rough spots in your car's acoustics. If you're looking for a little more punch, connect an amp or powered sub to the three sets of 4-volt preamp outputs.

Keep your factory features

The AVH-521EX offers compatibility you won't find in many other aftermarket radios, thanks to the iDatalink Maestro module (not included). In a wide selection of vehicles, this module lets you keep factory features that you'd otherwise lose when you install a new radio. You'll also be able to check out expanded functionality on the Pioneer's screen, including gauges, climate controls, a distance sensor, and tire pressure and temperature monitors. Once you've identified your vehicle, you'll see the iDatalink module offered on the way to your Shopping Cart if it's compatible.

You'll need a wired connection to your parking brake to access settings and other features on this receiver. Your parking brake must be connected and set in order to view video on its screen.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

The apps must be downloaded on your compatible mobile device and can then be accessed through the Pioneer receiver's touchscreen using the WebLink interface.

    • YouTube: With WebLink, you can access YouTube (for Apple iOS 10.0+ and Android OS 5.0+) and play videos on the Pioneer receiver's touchscreen monitor (your vehicle's parking brake will need to be engaged). You can select videos from a variety of categories or search by keyword(s).
    • Yelp: Yelp (for Apple iOS 10.0+ and Android OS 5.0+) uses automated software to recommend the most helpful and reliable reviews for the Yelp community among the millions submitted. The software looks at dozens of different signals, including various measures of quality, reliability, and activity on Yelp. Let Yelp help you find the best Restaurants, Hotels, Automotive Service Centers, Banks, Shopping Malls, and more. Search by Category, Favorites, Distance, Point on the Map, or Keyword. A keyword search requires that your vehicle's parking brake be engaged.
    • Zomato: Zomato (for Apple iOS 10.0+ and Android OS 5.0+) lets you search for and discover restaurants to eat out at or order in from. Browse through restaurant menus, photos, user reviews and ratings to decide where you want to eat, and use the map feature to guide you there.

If you need to control the WebLink app from your smartphone, you will have to disconnect your phone's cable from the Pioneer receiver.
    • The WebLink app must be opened as the primary app on your phone. If you press the home button or go to access other apps on your phone, the WebLink apps will pause on the Pioneer receiver, until the WebLink app is the primary app again. WebLink will not work with the app only running in the background.

During MTP connection, you cannot use your Android smartphone's touchscreen to control music playback and you cannot select music apps from your smartphone for playback. However, you can continue to listen to stored music on your Android smartphone through the head unit while you check your Calendar, Facebook, Texts, etc on your phone.

    Notes:

You'll need an Apple Certified Lightning or 30-pin cable to make connection. You can choose to control music playback and access music apps from the head unit or your compatible Apple device.

    • Category Search (ABC): From the head unit, you can browse your iPhone's or iPod touch's music library by Artist, Album, Song, Genre, Playlist, Composer, Podcast, or Audiobook. Once you have selected a category (playlist/song/artist/album/genre/etc.), you can search each category alphabetically (A-Z).
    • Link Search: Link Search allows you to play songs related to the currently playing song. Link Search lets the head unit create an album list of the currently playing artist, a song list of the currently playing album, or an album list of the currently playing genre.

    Audio Section

    24-Bit/192kHz DAC: The Pioneer AVH-521EX is equipped with a 24-bit/192Hz digital-to-analog converter for superb quality audio playback from disc, USB, iPod/iPhone, Android, and Bluetooth.

    MOSFET50 Internal Amplifier: The Pioneer AVH-521EX is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

    • CTA-2006 Specs: 14 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Continuous Power Output: 22 watts RMS x 4 channels (at 4 ohms, 50Hz-15kHz, 5% THD)
    • Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)
    Note: The power specifications for the AVH-521EX are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.

    4V/6CH Preamp Outputs + Sub Control: The Pioneer AVH-521EX features three pair of 4.0-volt preamp outputs (Front/Rear/Subwoofer). The unit's front and rear preamp output can be faded (front/rear), while the subwoofer preamp output is non-fading. The Pioneer AVH-521EX lets you adjust the subwoofer preamp output's phase (normal/reverse) and volume (+10 to -24).

    Crossovers: The AVH-521EX employs high-pass and low-pass crossovers to tailor the head unit to your connected speaker setup.

    • Standard: Allows you to set the high-pass and low-pass crossover network for a standard Front, Rear, and Subwoofer speaker setup using either speaker-level or low-level outputs.
      • HPF: The head unit's -6 to -24dB/octave high pass filter only allows frequencies higher than those in the selected range (50, 63, 80, 100, 125, 160, 200Hz) to your front and rear speakers through the unit's speaker-level or line-level outputs.
      • LPF: The subwoofer preamp output features an -6 to -24dB/octave low pass filter so only frequencies lower than those in the selected range (50, 63, 80, 100, 125, 160, 200Hz) are output to your connected subwoofer.
    • Network: Allows you to set the high-pass and low-pass crossover network for a complex 3-way speaker system with Highs, Mids, and Sub using low-level outputs only.
      • Highs: The high-pass crossover for your tweeters can be set to 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8, 10, or 12.5 kHz with a -6 to -36dB/octave roll-off.
      • Mids: You can set a high-pass and low-pass crossover from your midrange/midbass drivers. The high-pass crossover can be set to 1.25, 1.6, 2, 2.5, 3.15, 4, 5, 6.3, 8, 10, or 12.5 kHz with a -6 to -36dB/octave roll-off. The low-pass crossover can be set to 26, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz with a -6 to -36dB/octave roll-off.
      • Lows: The low-pass crossover for your subwoofers can be set to 26, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, or 250 Hz with a -6 to -36dB/octave roll-off.

    EEQ (Easy EQ) w/ 13-Band Graphic EQ: There are seven stored equalizer curves which you can easily recall at any time. You can choose from - Powerful, Natural, Vocal, Super Bass, Flat, Custom 1, or Custom 2. The Custom 1 and Custom 2 EQ modes allow you to manually adjust the level (+/- 12dB) of each band of the head unit's 13-band graphic equalizer (50, 80, 125, 200, 315, 500, 800, 1.25k, 2k, 3.15k, 5k, 8k, and 12.5k Hz).

    Auto EQ (Optional): The auto-equalizer automatically measures your car's interior acoustic characteristics, and then creates an auto-equalizer curve base on that information. The Pioneer CD-MC20 Auto-EQ microphone (130CDMC20, sold separately) is required to use this function. The Pioneer CD-MC20 Auto-EQ microphone plugs into your compatible Pioneer A/V receiver's rear-panel AUX 3.5mm input. The Auto-EQ microphone should be placed in the center of your vehicle's driver seat headrest facing forward for EQ measurement.

    Audio Settings: The head unit provides further sound adjustments for your car audio system.

    • Listening Position & Time Alignment: For a better sound-stage you can select your optimal listening position. You can choose from All, Front Left, Front Right, or Front. You can also select to manually fine tune the sound stage, using Digital Time Alignment (DTA) by selecting the distance (0-200") for each individual speaker in the vehicle compared to your listening position.
    • Advanced Sound Retriever: The Advanced Sound Retriever automatically enhances compressed audio and restores the original richness of the recording. When the Advanced Sound Retriever is on, the high frequency range is compensated to match the frequency response curve to the original sound. There are two available levels of the Advanced Sound Retriever effect.
    • Bass Boost: You can easily boost the subwoofer bass level by using the Bass Boost function. The Bass Boost feature allows you increase the subwoofer level from 0 to +6 (12dB).
    • Loudness: The Loudness function compensates for deficiencies in the low- and high-frequency ranges at low volume. You can set the Loudness to High, Mid, Low, or Off.
    • Speaker Level: You can adjust each speaker and sub channel independently from +10 to -24 to best even out the sound in your vehicle.
    • Source Level Adjustment (SLA): This function lets you adjust the volume level of each source to prevent radical changes in volume when switching between sources. Settings are based on the unit's FM volume level, which remains unchanged. Each source can be independently adjusted from -4 dB to +4 dB.
    • Auto Level Control (ALC): This function automatically corrects the audio level difference between the music files and/or the sources.

    Rear Speaker Setup: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.

    Beep Tone: The in-dash head unit provides an audible beep to confirm button operation. You can turn this feature on or off.

    AV + OEM Connectivity

    Dual AV Inputs: The Pioneer DVD receiver has dual AV inputs to connect two external audio/video sources. The head unit has a rear-panel 3.5mm minijack AV input for connecting a portable audio/video device. There is also a rear-panel composite video/stereo RCA AV input for connecting a video component such as a mobile TV tuner or game console.

    Video Output: A single RCA composite video-output jack allows you to an add external monitor, such as rear headrest or overhead monitor (sold separately). The video output can display a DVD, USB, or AV-input video signal when its selected as the receiver's source, regardless if the vehicle's parking brake is engaged or not.

    Camera Input w/ Parking Assist Guidelines: The Pioneer receiver is equipped with a composite video rear-view camera input for the addition of an optional backup camera (130NDBC8, sold separately). The unit provides on-screen guidelines to assist you when backing up and parking your vehicle. These guidelines do not automatically appear on the rear-view image. You must tap the "Park Assist Guidelines" icon on the touchscreen while the rear-view image is visible on the receiver's touchscreen. You can also turn the unit's composite AV input into a second camera input for adding a front camera (sold separately). The dedicated rear-view camera input offers two view modes -

    • Auto View: The unit features a function that automatically switches to the rear camera image. When the vehicle's transmission is put in reverse, the screen automatically switches to the rear view camera (violet/white wire of the harness must be connected to the vehicle's reverse lamp circuit for automatic video switching). Automatic video switching takes approximately 0.8 seconds.
    • Camera View: There is also a Camera View mode which allows you to manually bring up the rearview camera image on the receiver's touchscreen monitor to check what is behind you while driving. You can leave the Camera View mode on if you want to see the rearview image at all times; for instance when towing a trailer.

    Note: The rear view camera feature is meant as a back-up aid only; never solely rely on the rear-view camera when backing-up. In addition to using the rear-view camera, always look behind you to make sure everything is clear when backing up your vehicle.
