In-Dash Receiver Specifications

Receiver Size

Single DIN: 1 DIN dimensions will work with all single DIN installation kits we have to offer. Single DIN radios are the most common size for after-market stereos.

Single DIN slot with flip-out screen: The DIN stereo includes a retractable, flip-out screen. Before purchasing, make measurements to be sure there is no interference with dash accessories such as A/C vents or shift levers.

Single DIN slot with a larger face: Standard single DIN size, but the display is larger then the standard single DIN size. Due to the nature of the larger face, problems may arise when installing in particular vehicles. These stereos are great for single DIN slots where you want a larger screen.

1.5 DIN: This size is very uncommon in vehicles, however this size opening is most commonly found in Chrysler and Chevrolet vehicles.

Double DIN: Approximately 4-inches in height, this size is becoming more common every year. Prior to 2000, this size was typically only found in Japanese vehicles such as those made by Honda or Toyota. Now, it is becoming more popular for many vehicles to be fit with a Double DIN opening.

Single DIN
Remote Control
Allows control of specific features and functions from a remote control. Typically they are used to prevent button wear on your radio, or to allow easier navigation of menus.
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison.

50 watts x 4 channels
RMS Power Output
The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS rating, the louder and cleaner your music sounds. The RMS output figure is much more accurate than the peak rating when comparing products.
20 watts x 4 channels
Preamp RCA Outputs
RCA outputs, commonly known as preamp outputs, allow you to connect one or sometimes multiple external amplifiers. An in-dash receiver will commonly have one, two or three sets of RCA outputs that can be used to connect external amplifiers and other components. One pair of RCA outputs will typically provide a full range signal that can be used for most subwoofer or speaker amplifiers. Two pairs of RCA outputs can typically be configured as four full range signals, or also as two full range and two subwoofer signals. Three sets of RCA outputs will almost always produce four speaker signals and two subwoofer signals for use with multiple amplifiers.
3 Pairs (Front, Rear, and Subwoofer)
Dedicated Subwoofer Preamp RCA Output
A dedicated output that has a built-in low-pass crossover for specific connection to a subwoofer amplifier that powers a low frequency driver, typically a subwoofer.
Preamp Voltage
The preamp output rating is measured in volts (V). The higher the rating, the stronger the signal. This results in less unwanted noise being picked up.
4 volts
Built-In Equalizer
The number of graphic or parametric equalizer bands the stereo receiver is equipped with. The more EQ options, the more you will be able to adjust your music to your liking.
Display Color
The display color refers to the color of the text and or graphics on the receiver.

Multi-Color: When more than one color is on the display, for example one part of the text is white, while the other part is blue.

Variable-Color: The display colors can be changed by the user. If the default color of text/display is blue for example, the user can change the settings to where the color turns to red. Variable color displays are typically described in detail in the item's description.

TFT-LCD Display: In-dash receivers with a video screen that display multiple colors and often times video such as DVD, navigation or other video sources.

Button Color
Refers to the color of the physical buttons on the unit.
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.


Playback Features

AM/FM Tuner
Most in-dash CD players have AM/FM playback allowing you listen to your favorite local radio stations.
FM Presets
The number of FM radio stations that can be stored as presets.
AM Presets
The number of AM radio stations that can be stored as presets.
CD-R/RW Playback
This feature refers to whether or not the CD player will play finalized CD-R discs and/or CD-RW discs.
MP3 Playback
This feature refers to whether or not the CD player will play discs encoded with MP3 files. To burn a MP3 encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.
WMA Playback
This feature refers to whether or not the CD player will play discs encoded with WMA files. To burn a WMA encoded disc, use the "data" mode on your CD Recorder and finalize the session and/or CD.

Expandability Features

Additional Audio/Video Inputs
These inputs enable the unit to receive an audio or video signal from a separate source. There are many different types of connections and ways to accomplish this. Most common are RCA Composite cables and 3.5mm mini-jack plugs.

RCA Composite Inputs
These are your typical red, white, and yellow RCA composite cables that are common among devices with audio and video inputs. The red and white cables are dedicated for audio. The red cable is for the right channel and the white is for the left channel. The yellow cable is specifically for the video signal. Because this type of auxiliary cable contains 2 channels of audio, it will support stereo sound.

This is commonly referred to as a mini-jack or a headphone jack. It is a 3.5mm plug that transfers audio only. There is a right and left audio channel on the plug which allows for stereo sound playback.

3.5mm AV Input
These plugs look similar to the common 3.5mm mini-jack, however they carry a third channel dedicated for video.

This means that an auxiliary input is possible, but only with the use of an optional accessory. These optional adapters will sometimes use the CD Changer port or other port on the back of a unit that might restrict the use of other expandability features. These accessories are typically sold separately.

Front 3.5mm Audio Input
USB Input
This feature refers to whether or not the receiver features an input to connect a USB device via standard USB or mini-USB. The USB input may be a connection on the front or rear of the unit with an extension cable for connecting devices to the receiver. Some units have an optional input that allows for a USB adapter to be purchased separately and used with the unit.
Satellite Radio
This feature signifies whether or not the receiver is compatible with XM or Sirius Satellite Radio. "Optional" means while the receiver is capable of SIRIUS/XM playback and connectivity, you will still need to purchase an additional satellite tuner, adapter, and/or antenna.
Optional - SiriusXM (Accessory required and sold separately)
HD Radio
This feature refers to whether or not the receiver is capable of receiving high-definition digital HD Radio broadcasts by either a built-in HD Radio tuner, or more commonly with the purchase of an optional HD Radio tuner box. Receivers which are HD Radio Ready generally require an additional purchase of a separate tuner.
Steering Wheel Control Compatible
In order to retain a vehicle's factory steering wheel remote controls, a wired-remote input is needed on the aftermarket stereo.

If "Yes", then the aftermarket stereo is compatible with steering wheel remote controls. If an additional accessory is required for the steering wheel controls to work properly, a compatible piece will be listed.

Yes (Accessory required and sold separately)
Memory Card Reader
Whether or not the receiver has a built-in input for removable memory cards such as SD (Secure Digital) cards or MMC (Multimedia) cards.

Great radio for boat or motorcycle

May 15, 2017

I had a Clarion M505 in my boat and really liked it. I had a different stereo on the after market fairing on my motorcycle, It was blue tooth and rang through the speakers when I got a cal. It had low level RCA outputs for the amp causing distortion at higher volumes. Also, it was a car stereo and unlikely to hold up to the conditions. I decided to install an M505 on my bike since it is blue tooth that doesn't ring when I get a call. It has high level RCA outputs with the aux in and USB are on the front, making them convenient.

Clarion M505

April 17, 2017

I used the M505 to replace an older Clarion M455 unit on my boat because it did not have a dedicated sub output or bluetooth. The M505 fit exactly in the same hole without modifications. I have two wired remotes CMRC1 that did not work with the M505, I had to install a special adapter cable to go from the 6 pin to the new 8 pin DIN connector. While the old wired remotes do work with the M505, the displays light up but do not show anything. The M505 was easy to set up and is intuitive to control. Since I have an aux input on my dash, I would have liked an Auxiliary output in the back of the unit like the M455,

Good quality and price.

I'm replacing older Clarion (CMD4) o my boat. The Clarion M505 has the features that I want and I can keep the 3 existing wired remotes at $129 each. I need an adapter cable for the M505, but I won't need 3 new remotes, extension cables, etc.

Can this unit M505 be used with the Clarion MF1 marine remote control. Can you stream Pandora through Blue tooth from an I Phone 6?
Kenneth T on Nov 17, 2015
Best Answer: I believe it can. I have the model with the display and I can stream from my iphone or my android phone via bluetooth.

Can this play music from my IPHONE 6 wirelessly?
A shopper on Aug 13, 2016
Best Answer: Yes, through bluetooth. We all have Iphone 6's and we switch between phones when listening to music on the boat. Also, MF1 is a nice addition for a wireless remote, just don't submerge in water for very long, will stop working until in dries out. Overall very happy with purchase!

I lose my settings when I turn the boat off so how do I save my settings?
A shopper on Jul 12, 2016
Best Answer: You can turn off your stereo and not lose your settings. It's when you shut off power to the stereo that there lost. You would have to reroute your power supply to a constant hot circuit instead of an ignition accessory circuit. Be sure to turn off your stereo when not in use so you don't drain your battery!

Is Clarion 505 compatible with Clarion Mf1 RF remote?
A shopper on Jun 23, 2017
Best Answer: Not sure...thought is only IR. However I don't use the remote at all as the unit is in the cabin we are normally on the outside deck.


Good unit though.

Can I hook up my cd player to this ?
A shopper on May 8, 2016
Best Answer: That depends on what the cd player output is. If you have an older cd changer then probably not. If you have a usb cd player then yes you can. There are no provisions on this deck to plug in the old style clarion cd changers.

Best Answer: Yes, it has had no issue remembering presets and settings when we switch the battery off in our boat.
