Our take on the Clarion M508

Clarion's M508 digital media receiver lets you stream music from your smartphone or any Bluetooth device to your boat's sound system. Bluetooth aptX processing (also found in many Android smartphones) restores the sparkle that's lost during compression, so you'll enjoy much better sound quality.

Merrily, merrily down the stream (-ing music)

Clarion logo

Clarion's M508 digital media receiver lets you stream music from your smartphone or any Bluetooth device to your boat's sound system. Bluetooth aptX processing (also found in many Android smartphones) restores the sparkle that's lost during compression, so you'll enjoy much better sound quality.

Shape your sound your way

Clarion built this rugged marine receiver to last, but it's also designed to deliver outstanding sound. The 3-band parametric equalizer lets you adjust the highs, mids, and lows to suit your preferences, and you can use the built-in frequency filters and subwoofer controls to get the best possible performance from your system. You'll find the four sets of preamps handy if you're adding amplifiers to your sound system.

Dual zone control lets you split the boat into two distinct areas to suit your needs, one zone powered by the radio and the second by an external amp (sold separately). You'll be able to crank up the bow speakers and leave the cabin speakers at a more conversational level.

Make the most of your music sources

The M508 gives you mastery over your music collection. If you're a Pandora® Internet radio fan, you can listen to your favorite stations when your iPhone's connected via USB. Song and artist information shows up clearly on the sharp-looking black-on-white 2-line display.

If you've ripped your entire CD collection and gone digital, you can plug a thumb drive into the front USB port and enjoy all your favorite MP3 or WMA tunes, or you can play your digital music player through the handy front AUX input. You can also enjoy the vast array of programming on satelllite radio by connecting a SiriusXM tuner (sold separately, subscription required).

Tune into terrestrial radio

Clarion's excellent AM/FM tuner hauls in plenty of local radio stations, no matter where in the world "local" might turn out to be. You'll also be able to get the latest on changing conditions from the Weather Band.

The black-on-white face makes it easy to see what you're tuned into at the moment, and the controls make changing channels or sources a breeze, even when you're underway.

Marine-rated durability

Clarion has earned its reputation for building marine electronics tough enough to withstand salt water, heavy fog, blistering sunlight, and lashing rain. The M508 is a versatile, multi-source receiver that's tough enough to handle the extremes of a marine environment.

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.

iPod/smartphone note: If you're going to use your iPod or smartphone with this receiver, be sure to check "Details" for compatibility information.

    Great product!

    Derrick from Washington, DC on 2/28/2019

    Crutchfield Customer Review (What's this?)

    I love this receiver! It is a very elegant product. I like how it blends in. It does everything that a modern stereo should (Bluetooth, SiriusXM, FM, Pandora, Aux in, USB) but it is not flashy. It will even connect to the NMEA 2000 network and has an option for iOS app based remote. The installation instructions were easy enough to follow and it has been performing very well for the last month. I use the built in amp for the cabin speakers (JL Audio6.5 in) and the pre-amp outputs for the fly bridge speakers and a sub.

    Pros: Simple and elegant looks, pre-amp and amp speaker output, supports pretty much every music source available

    Cons: The screen is simple and small so it might be difficult to read text (but why do I need to read the screen when I'm streaming from my phone?)

    Sounds great. Easy to use!



    Nice and simple

    Crutchfield Customer Review (What's this?)

    Install was a BREEZE!! (although previous deck was also an older Clarion). Connected to speakers, remotes, amp with little trouble. Easy to use, clear display. Not the least expensive one out there but after a month, no complaints, probs or difficulties.

    Pros: Simple to operate, connectivity was great.

    Cons: A little expensive.

    Crutchfield customer from Wilmington, MA on 7/15/2018

    Crutchfield Customer Review (What's this?)

    Not bad. The settings and controls are confusing. Cannot use my andriod phone via USB, but Apple works. Inuse Bluetooth. Does not come with an xmradio antenna. Overall good purchase.

    Pros: Easy swap from my old Clarion. They still use the same harness plug.

    Cons: No usb with andriod. Menu clunky

    Simple to use

    Pete from Wichita, KS on 7/10/2018

    Crutchfield Customer Review (What's this?)

    Easy install, just spliced the wires to the matching colors since I didn't have an adapter. This device is simply to use and easy controls to follow. It connects directly to Pandora so I can rate the song from the device. The menu is very clear and easy to navigate through. The mute is the volume button, which is awesome! The Bluetooth is the easiest I have seen for a head unit and it displays what is connected so you are not trying to figure out who's device it is.

    Pros: Mute button is the volume knob, easy to connect Bluetooth and displays what is connected


    Great stereo for boating

    Laura from Bay Village, OH on 6/8/2018

    Crutchfield Customer Review (What's this?)

    Great radio for a reasonable price. I had the m303 on my other boat. I purchased this one as an upgrade to my new boat. Easy to use and comparable with my iPod.

    Pros: Easy to use. Bluetooth.


    Perfect for everyday

    Brandon from Burlington, NC on 6/2/2018

    Crutchfield Customer Review (What's this?)

    Money well spent

    Pros: Don't have to use aux cord for music but you can if need be

    Cons: You must buy a microphone for you to be able to talk on the phone and hear it from speakers so it kinda forces you to talk on speakerphone

    Marine, Display, & Remote Features

    Marine Tested: The Clarion M508 Marine digital media receiver has been engineered and tested for use in the harsh marine environment. The M508 meets ASTM B117 and ASTM D4329 guidelines ensuring the receiver's resistant to salt, fog and UV exposure. The receiver features a drip shield chassis to keep water from dripping onto the unit's internal circuits. In addition, the head unit's PCB and microprocessor are conformal coated to protect them from corrosion. It also has low power consumption when powered off.

    High Visibility LCD: The two-line, 13-digit, high visibility LCD (with bluish white background and black characters) on the M508 allows numbers and characters to be displayed clearly in almost any lighting condition. The display's backlight brightness can be set to High or Low. You can turn the display's backlight off in the event the display is too bright in different lighting conditions.

    Water Resistant Covers (optional): Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover (sold separately - see Accessories Tab)

    Optional Wired & Wireless Remotes: The unit is equipped with a rear mounted 8-pin DIN connector to accommodate optional Clarion wired & wireless remote controls. 

    • Wired Remote: The MW1 (sold separately) is a hardwired remote control with an LCD screen. The MW4 (sold separately) is a more advanced wired remote with a 2.8" color LCD screen.
    • RF Remote: The Clarion MF1 (sold separately) is a RF remote control which is waterproof and designed to float. The MF1 meets or exceeds ASTM B117 (Salt/Fog Exposure), ASTM D4329 (UV Exposure), and IP67 (International Protection Rating).
    • WiFi Remote Module: The Clarion MF2 marine remote module (sold separately) features built-in WiFi and allows you to control the Clarion marine receiver via the free Clarion MF2 app on your Apple iOS 6.0+ device.

    Note: When two remotes are used in combination with one another, Clarion's MW-RYC-RET Y-adapter (sold separately) is required.

    Optional NMEA 2000 Interface Module: Clarion's MW6 NMEA 2000 Compliant interface module (sold separately) allows Clarion marine source unit to be seamlessly added to your boat's onboard NMEA 2000 network, enabling control and two-way communication of the Clarion source unit directly from the boat's Multi-Function Display (MFD) device. Control functions include source and track selection, play/pause, and more.  Two-way communication between the Clarion source unit and your MFD allows source selection, song/track/ album title, radio frequency and more to display on the MFD interface.

    Bluetooth & iPhone Integration

    Wireless Audio Streaming: The Clarion M508 supports wireless audio playback (AD2P 1.2) and control (AVRCP 1.4) of a Bluetooth-enabled smartphone or audio player, plus song/artist information display and support for aptX music streaming. You are able to wirelessly stream your stored music library, music apps, and other content on your Bluetooth source device to the Clarion marine receiver.

    • SBC + aptX Codecs: In addition to support for the standard SBC Bluetooth audio codec, the M508 incorporates the Qualcomm's lossless Bluetooth aptX codec (primarily for Android OS 4.0+ devices) which helps retain sound elements lost during digital compression of audio files, ensuring users the ability to always enjoy high quality sound with wireless convenience. 
    • Control & Display: In addition to basic playback functions (Play/Pause, FF/RW, Skip, Random/Repeat), the M508 lets you browse your stored music by Playlist, Artist, Album, Song, etc. (AVRCP 1.4 phones only; which includes Android 4.0+ and iPhone 5.0+). The head unit will also display your stored music and music app's song information; such as Artist name and Song/Album title (not compatible with all apps).
    • Simple Secure Pairing (SSP): With Secure Simple Pairing (SSP), you can easily pair a Bluetooth device to the Clarion M508 without having to enter pin codes or go through complicated settings. When a paired Bluetooth device is in close proximity to the receiver, the auto connection function automatically pairs the two units. You can pair up to three Bluetooth-enabled devices to the Clarion head unit, but only one can be used at a time.
    Note: When an incoming call or outgoing call is in progress from your Bluetooth enabled phone, audio streaming will be paused so you can take your call. Once the call is finished, your streaming music will resume.

    Optional External Mic: You can purchase Clarion's RCB-204 optional external mic (sold separately) to add Hands-Free Communication and Siri Eyes Free Control to the Clarion M508 marine receiver.

    • Hands-Free Communication: The M508 allows you to answer and end phone calls from its front-panel controls. When a call comes in, a ring-tone will be heard through your speaker and the phone number will be displayed. The optional mic (sold separately) is used to carry on your side of the conversation, while your speakers are used to listen to the other party. You can make a call using voice recognition, if your phone supports voice dialing (Siri for iPhone and Google Voice for Android). The M508 does not allow you to manually enter a phone number, download your phone call, or create phone presets.
    • Siri Eyes-Free Control: When paired and connected to an iPhone with Siri via Bluetooth, the M508 has the ability to access Siri through its front-panel controls and optional external mic (sold separately). Simply press-and-hold down on the head unit's Answer/End button to engage Siri and use the optional mic to communicate with Siri. Siri's voice will heard through your vehicle's speakers. All Siri functions including hands-free calling, music search, setting reminders, text-messaging, audible navigation, and more can be done through the M508 and the optional mic. You even can ask Siri to get directions to a destination and the turn-by-turn instructions will heard through your vehicle's speakers, while the on-screen map still displays on your iPhone with Siri. The head unit's audio is attenuated while Siri provides audible directions.
    Note: In addition to the Clarion RCB-204 external mic (sold separately), you'll also need to activate Hands-Free Communication within the receiver's menu (be default it is turned off).

    iPod/iPhone Direct Connection: The Clarion M508's front-panel USB port lets you connect select Apple iPods and iPhones for music playback. Simply use the cable that came with your iPod/iPhone device or an Apple certified cable (sold separately). The M508 supports audio playback, control, display, and charging of your compatible Apple device.

    • Control: The Clarion head unit allows you to navigate your Apple device's music by Playlist, Artists, Album, Genre, Composer, Song, Audiobooks, or Podcast. These categories and music files inside these categories will be listed alphabetically. The head unit also controls Play/Pause, Previous/Next Track, Fast-Forward/Rewind, and Random/Repeat functions. You can also continue to use the touchscreen of your connected Apple device (running iOS 6.0 or newer) to access additional music apps and other playback options. Older iPods and iPhone's will be locked during connection.
    • Display: The head unit will display artist name, song title, and album title from your Apple devices stored music library and select music apps (not compatible with all apps).
    • Charging: The head unit's USB connection provides 1A of current to power and charge your connected iPod/iPhone when your vehicle's ignition switch is set to the 'ACC' or 'On' position (if your iPod/iPhone has no initial battery charge, then the unit will not recognize it).

    Pandora Internet Radio: The free Pandora App (for Apple iOS 10.0+ or Android 4.0+) lets you play music from the Pandora music service through the Clarion M508 using your USB or Bluetooth connected Apple iPhone, or Bluetooth connected Android smartphone. The M508 provides control over the Pandora music service and displays Artist, Album, and Song information. Your iPhone or Android smartphone will need an active Data Plan account with connection to the Internet via 3G, EDGE, LTE (4G) or WiFi. You will also need a Pandora music service account.

    • Music Control: The M508 provides control over the Pandora music service. You can select Pandora stations from your station list and sort them by date or alphabetically (A-Z). New stations can be created based on the current songs or artists playing. You can also skip song tracks within a station. You can even give songs a thumbs up or thumbs down or bookmark songs/artists that are currently playing.
    • Song/Artist Display: The M508 will also display your Pandora station's song/artist information such as artist name, song title, and album title.
    Note: Access to the Pandora  service will depend on the availability of a cellular and/or WiFi network for purposes of allowing your iPhone or Android smartphone to connect to the Internet. Pandora is not supported in Canada and is only available in the United States.

    SiriusXM-Ready: The Clarion M508 is SiriusXM-Ready and compatible with the SiriusXM Connect Vehicle Tuner (220SXV300 sold separately).

    • Parental Lock: Channels containing unsuitable content for children can be blocked.
    Note: A separate SiriusXM Satellite Radio subscription is required (operates on the XM Network). However, you can easily add this SiriusXM tuner to an existing Sirius or XM account for a Multi-Radio Discount Plan.

    Global Radio Tuner w/ Weather Band: The built-in multi-band tuner supports reception of radio stations just about anywhere in the world - which is nice when you're sailing around the globe or just across the gulf. And with Weather Band you'll always have the latest weather updates, including automatic reception of emergency weather information to keep your voyage as smooth as possible.

    • AM/FM Radio: The Clarion M508 is equipped with a built-in AM/FM tuner offering manual, seek, and preset tuning (with preset scan). 18 FM station presets and 6 AM station presets can stored; stations can be stored manually or automatically. Preset scan lets you quickly scan through all of your preset stations in a selected band. This function is useful when searching for a desired preset station. When Local seeking is turned "On", only those radio stations with strong radio signal can be received. This unit's tuner is initially set to USA frequency intervals, but can be changed to Europe, Australia, and other countries tuning.
      • USA: FM (87.9-107.9 MHz) / AM (530-1710 kHz)
      • Europe: FM (87.5-108.0 MHz) / AM 531-1602 kHz)
      • Australia/Other Countries: FM (87.5-108.0MHz / AM (531-1629 kHz)
    • Weather Band: Weather Band channels include - CH1 (162.400MHz), CH2 (162.425MHz), CH3 (162.450MHz), CH4 (162.475MHz), CH5 (162.500MHz), CH6 (162.525MHz), & CH7 (162.550MHz).

    Audio Section with Dual Zone

    MOSFET Amplifier: The Clarion M508 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. The power output specs for the M508 are as follows:

    • CTA-2006 Specs: 18 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 50 watts x 4 channels (200 watts total)
    Note: The power specifications for the M508 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 RCA Outputs: With 6-Channel/4-Volt RCA Outputs, you are free to add external power amplifiers to create a more powerful, sophisticated audio system. What's more, the 4-volt output assures a pure, high quality signal for your entire sound system. The non-fading subwoofer preamp output features an independent level control (0-12).

    3-Band EQ + Presets: The Clarion M508 incorporates a 3-band EQ and 11 EQ presets. The EQ presets consist of Flat, Jazz, Pop, Classic, Rock, News, Urban, Rave, Movie, Techno, and User. The User preset allows you to adjust the head unit's 3-band EQ (Bass, Mid, & Treble) from -7 to +7. EQ settings are applied to all sources.

    Dual Zone Audio with Fixed Output: The Clarion M508 is fitted with a stereo line-level output (fixed) for Dual Zone audio ( requires an external amplifier in Zone 2). With this function, it is possible to split your boat into two discrete zones to enjoy different volume levels of the same audio source. For instance, the bow can be tuned-in to a higher volume level for enjoyment in the wind while the stern can enjoy the music at a lower volume to accommodate conversations. Volume levels from the fixed zone are controlled by optional external volume control device or "pot" (sold separately). This is ideal for separate areas such as salons, wakeboard towers, and open bows.

    Beep Confirmation: The marine head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

    Q & A

    Customer Q&A

    Crutchfield asked  
    Why did you buy this?

    Its marine grade and Clarion is a great brand. [ SEAN C  Oct 12, 2018 ]
    This head unit is bluetooth compatible as well as remote compatible. [ Mark  Jul 30, 2018 ]
    I currently have a Clarion in my boat, hope this will be more compatible and easier to install. Also, anticipate that it will match up with wired remotes and the Clarion 6-disk changer already in. Tks!! [ Randall  Jul 16, 2018 ]
    Features - iPhone connectivity. No CD [ Allen  Jul 04, 2018 ]
    needed tunes!! [ DEVIN J  Jun 25, 2018 ]
    Because it works with the marine remotes for my boat [ S  Jun 01, 2018 ]
    Will use on motorcycle, conformal coating of circuit boards will help with water resistance. Liked the spec and if Crutchfield are selling it, I know it is a good unit. [ StuDad  May 21, 2018 ]
    Have older Clarion in boat. Hoping this will be easier to install and wire? [ James  May 16, 2018 ]
    Already had the remote....that I was told would work with this unit! [ Scott  May 02, 2018 ]
    I chose this model simply because it's literally the only aftermarket single din head unit on the market that doesn't look like one of Megatron's bowel movements. Clean, simple design that looks good in any car. Thank you Clarion! [ Steven  Apr 14, 2018 ]
    Looks to be the best single din radio with marine capabilities, only missing the IP ratings of true boat radios. I bought this for my Jeep Wrangler because my last radio broke after I got caught out in the rain without the top. This radio has the usual coating on the pcb but also features a drip tray, which should hopefully help in the rain. [ Gerard  Apr 09, 2018 ]
    Bluetooth, marine, name recognition. [ Jason  Mar 12, 2018 ]

    7 questions already asked

    Hi. It did receive phone calls but I did not attach the optional mic. In the end, I returned this unit because of the inability to control volume from my phone. Also, the Clarion optional remote I already had attached to current stereo would not work with this one. [ Chris  Nov 26, 2018 ]
    Sorry but I have never tried it wish I could help [ RICK  Nov 26, 2018 ]
    Yes, one reason i chose this unit was a really highly rated bluetooth system. You will need to get a mic though (it didn't come with one). [ John  Nov 26, 2018 ]
    I returned this item, never hooked it up [ Tony  Nov 26, 2018 ]
    You would have to use optional microphone [ Steven  Dec 04, 2018 ]
    Nope. It does not have a mic. [ Brent  Dec 03, 2018 ]
    I'm not sure of the range. My ski boat is probably smaller than your boat though. I don't have a cabin. Farthest distance I've been from the boat is about 6-8ft and I've never had a connection problem. [ Chris  Jul 19, 2018 ]
    We need someone to answer this. I also installed this unit and cannot control the volume through my iPhone. My phone volume works fine with ANY other BT device [ Tatu22  Jul 06, 2018 ]
    Yes, installed the M508 a few weeks ago and noticed the lack of volume control through my phone. I was thinking it has something to do with the "Dual Zone Audio with Fixed Output" but really just guessing. Probably need a Crutchfield expert to explain it. [ Angela  Jun 24, 2018 ]
    For me, the buttons were white and the screen had a blue hue to it. There are no colour options. I returned this unit as it did not connect well all the time with my iPhone7. There was no native Spotify support. Also the seek/play etc buttons around the knob are thin/small and not easy to touch/use. The lookis period correct for older cars which is great but for me, thats abou tit. [ TIMIR  Jun 04, 2018 ]
    The buttons are white bright you can cut the display off though with a push of a button [ Brandon  Jun 03, 2018 ]
    According to Clarion's website, the Clarion CMRC1-SB remote would only work with Clarion's CMD4, CMD4A, CMD5, M455, and M475 marine receiver models. However the M508 is equipped with a rear mounted 8-pin DIN connector to accommodate optional Clarion wired & wireless remote controls; including the MW1, MW4, MF1 and MF2 models.
