Item #: 158CDXM20
This item is no longer available.
Don't settle for a regular car CD receiver in your boat — choose one that's built to stand up to the demands of the marine environment. Sony's CDX-M20 marine receiver uses a UV coating to protect the face from sun damage, along with a conformal-coated circuit board that resists moisture. It'll keep your boat rocking for years of fun on the water.
Plenty of ways to play your music
You can play your store-bought and recordable CDs on this Sony, including discs you've loaded with MP3 or WMA files. For more variety, you can jack your iPod® or any other portable into the handy front-panel auxiliary input.
Satellite radio is a big favorite with boaters, because of its great offshore reception. You can plug an optional SiriusXM tuner into the CDX-M20 an enjoy an unparalleled variety of music, sports, talk, and news.
The 3-band equalizer tailors the sound for the perfect blend of lows, mids, and highs, while high- and low-pass filters let you send the right frequencies to the speakers and amps in your setup. Sony includes a convenient wireless remote. The CDX-M20 is also compatible with Sony's RM-X11M wired marine remote control.
Installation notes: This marine radio is water-resistant, but we recommend mounting it in a water-resistant enclosure or using a cover for best performance.

Has Good power. Needs to take abuse in a boat and seems to do that.
Great product, no issues.
This radio came with everything needed to adapt to my motorcycle. I could not be more pleased. Much cheaper than a harley radio which harley does not even support anymore. I would use Crutchfield again.
Pros: radio fits perfectly
Cons: Could use better instructions
Very impressed with the options that came with the unit
Cons: Have not had any problems with the unit yet
Excellent CD player for the money, has an easy to read display screen, even in bright sun light. Perfect amount of power, I ordered a separate amp, but have not even installed it because the deck seems to have more than enough without it. The install was a bit time consuming because the wire harnesses didn't match up so I had to identify all the wires and splice them all together, however when it was all completed it sounded great and got excellent reception from my AM/FM antenna. I would strongly encourage getting a marine grade as they seem to have much stronger am/fm antenna capabilities I have noticed. I also have a Sony CD player/deck in my 1996 Tacoma and the CD in dash player/deck is about 15 years old and still playing like a champ! I would have given the review five starts if the installation wasn't so much of a pain. Also make sure you get a CD player install kit that comes with rails so that the mounting is secure in your boat. When I purchased this CD player they didn't have any available for a pontoon boats so my new CD player was installed using parts I could find around the garage. It still works great, but am looking for a better way to have it mounted in the Pontoon. On my next CD Player I order I think I will make sure and get Bluetooth capability built in as this one didn't have it and having the wireless capability is nice. I ended up buying a $20 adapter that seems to do the trick for now.
Pros: Great AM/FM CD player for the money with easy to read front screen even in sunlight and AUX IN, right on the front screen, Plays loud and is very durable...
Cons: Installation was a little bit more time consuming than I originally planned and there was no mounting kit or rails with the deck to match up to the Pontoon Boat, along with No bluetooth capability built into the deck.
I had this unit installed in my boat for less than 4 months. I used the boat 4 times since then. The radio is in a dry location. I was getting the boat ready for another trip and the unit would not come on. I unplugged it, plugged it and it turned on but the display just goes through the features (demo mode). It won't come out of that mode onto any source.
Pros: Ok while it lasted.
Cons: Short LifeCrutchfield response on July 11, 2016 Whenever you encounter a problem with anything you purchase from Crutchfield, please contact our tech support team right away. Lifetime tech support comes with every Crutchfield purchase.
Bought the stereo to replace the Sony unit that came with a Four Winns boat. Installation was fairly easy with some slight modification to the rear mounting brack. Stereo sounds great with new Sony 1611 speakers.
Pros: Easy to use and understand controls. Wiring was very easy and basically just plug and play.
Cons: Stereo mounting bracket does not secure from the front and requires some creativity to fasten the unit behind the dash.
Great stereo for our boat at a great price.
Pros: Came with the remote commander and a handheld remote too.
Cons: Single line display.
We loved this Stereo. Easy installation, great sound and quick delivery.
Pros: Great sounding Stereo
Cons: No cons
This radio works wonderful
Haven't had opportunity to use much as it is installed on my boat. Still figuring out all options. Thus far a really nice product, easy to install.
Pros: Easy installation
Great head unit! It sounds great and the blue looks amazing. It makes my boat's sound system over the top. I am so happy to finally be able to connect my music device
Pros: Great unit!, Clean sound
Groovin to tunes again! Marine, detachable face, line in, cd, luminates blue, remote, dig it!
Pros: remote sweet!

I bought this to put in my golf. Very satisfied with every aspect of this unit.would highly recommend it to anyone who needs a waterproof stereo.
Pros: Looks great,works great,easy to install.What else is there today Looks great,works great,easy to install.What else is there to say.
Cons: I have no cons on this stereo.
good, relatively simple, no nonsense marine radio. easy to install. haven't used the wired remote, but wireless is fine as long as there is a direct line of site to the radio.
Pros: simple, no frills, radio
Cons: manual a bit confusing. some features either not there or not explained .
Amazing product! A little hard to figure out settings at first.
Installed it in my boat for better sound quality and it lived up to the name. The looks of it did as well. Couldn't have asked for a better product for the price. Looks great and sounds great.
Pros: -Sound quality it produces -Faceplate design -Easy installation -Installation instructions very detailed
Cons: No bad things to say about this product.
Pros: Sounds good .. easy to use
Reception and sound are fine. Controls are difficult to use and dial light remains on.
Easy to install --works perfectly
Well designed, easy to use controls and sensitive receiver
Always seem to be coming up with odd install for the staff at Crutchfield. This particular one was no different. I needed marine grade stereo & speakers to install in a golf cart that had space limitations. Typical install is buy overhead console from golf cart accessory shop & straight forward install from there. However due to 5 panel rear view mirror & retractable tow strap that was not an option. Golf cart is used at race track as support vehicle/goofing around in pits. On to stereo-unfortunately had to test out after install & it was pouring rain. Stereo did great, sounds good & bonus remote worked killer. Paired with Infinity marine speakers & cant wait for summer time pit hopping
Pros: Water resistant, wireless remote, great sound & all the options plus some
Cons: none found yet
Good radio reception good system for the price arrived sooner than Crutchfield said it would
This stereo was easy to install and the sound is amaziing. I put it on my boat in less than 15 minutes. The installation couldn't have been easier and as I mentioned the sound is outstanding. I am picking up radio stations that I can't pickup in my vehicle.
Pros: easy install and great install.
I am very satisfied with the sony reciever I purchased for my motorcycle. It sounds awesome!!
Nice stereo, great price, great service from Crutchfield. Had read some negatives about distortion at high volume with the bass but have not notice that. Plus it is a Sony, which should be built pretty well. This unit is cheaper than the M30 model yet I believe it performs the same, just not as many bells and whistles.
Pros: Easy installation, great sound, similar to the stereo I put in my car so features work the same. Like the Aux input for my mp3 player to the point that I have not even used a CD yet. Like the feature where the name of songs are displayed on the LCD screen (data system).
Cons: Would have rather not had a detachable faceplate since it is another connection/failure point plus it pops off too easily if you bump the button. I used the small screw that came with the stereo that said it was for dealers only to secure the faceplate on so it would not or could not be removed without removing the whole unit first.

I have 2 boats and purchased this radio recently for 1 boat and it works great. Unfortunately some one went only second boat and stole the face plated of my Sony radio!!!!! It costs too much to get a replacement face plate so I just bought another radio. [ james Aug 21, 2016 ]

I did a little bit of research and this seemed to be a good quality marine stereo for a relatively minimal price. [ Christopher Feb 07, 2016 ]
Sorry, don't know. We ignore the clock because we kill all power whenever we leave the boat unattended, so the clock loses its setting. Perhaps someday someone will make a marine receiver with a small internal battery to hold the time when the line power is cut [ James Nov 05, 2016 ]
Sorry, can't help you. We mounted the radio in our boat with the supplied system, and it is quite secure. [ James Jul 29, 2016 ]
