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
Faceplate Security

Detachable / Removable faceplate security: The most common anti-theft feature. It allows you to take the faceplate with you, thus disallowing operation, which deters theft.

Security Codes: Mainly a feature in high end video units which do not have a detachable face / screen. Once the unit is uninstalled (or stolen), a security code (or PIN) is required upon reinstallation. Though you no longer have your unit after the theft, the thief also does not have your security code, which makes the unit useless. The hope is the thief knows which units have security codes and he/she chooses not to steal your unit because of the security code.

Ghost technology: This is not commonly used, but can be found primarily in a select number of 2004-2005 head units. It creates an illusion that no unit is installed by appearing completely black when turned off. Potential thieves may steer clear because it appears as though no head unit is installed.

Anti-theft covers: Similar to ghost and hiding faces because they only create an illusion that the face/unit is not in place.

ESN: Stands for Electronic Serial Number. Allows the disabling of the radio and allows tracking if it is stolen.

Detachable
Motorized Faceplate
Some in-dash car stereos feature a motorized faceplate that moves to expose a CD or DVD slot. This is a convenient feature that allows the front display to be larger and easier to read. The positioning of the monitor gives you control over the angle you would like to view information on the stereo.
No
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.
Yes
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.

52 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.
17 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.
Yes
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.
2 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.
EQ7
Display Type
The type of display on your receiver refers to the monitor that is used to display the source information such as song names, radio stations, or track times.

Dot-Matrix Text Display: A simple display which uses dots in specific illuminated color(s) to light up and form letters or numbers that are displayed on the receiver.

Graphic or Motion Display: Typically found in mid to high-end receivers and give your text information and receiver more life by adding motion, backgrounds, or multiple colors to your display. There are types of graphic displays such as 3D Graphic, Motion, and OEL (Organic Electroluminescent) displays. They can range from one color to full color displays and typically allow you to select from one of many built-in animations, background images, screensavers or other graphics to enhance your experience and add an extra bit of personality to your system. Some units also come with software that allow you to load your own customizable pictures or animations.

LCD Monitor Display: Can be as small as 2" or as large as 10". Some LCD displays are motorized for angle adjustment. LCD monitors display full motion video playback as well as your standard text such as track status, radio station information and more depending on the receiver's features.

LCD Text Display
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.

White
Button Color
Refers to the color of the physical buttons on the unit.
Blue and Red
CD Signal-to-Noise
CD Signal-to-Noise Ratio is a key specification that is often overlooked by newbies. The CD S/N Ratio measures how well the CD player silences background noise. Higher ratings in decibels (dB) indicates less noise, and generally a cleaner signal.
120 dB
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.

Yes

No

Audio / Video Inputs

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.
Front
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.

3.5mm
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.

Optional
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

Expandability Features

Navigation
Built-in navigation is a convenient feature that allows the driver to receive driving directions and guidance.

Some in-dash head units are built-in with the navigation features, while others require an add on navigation box. Other navigation options include portable navigation units that you can take with you or attach to the dash of your vehicle.

No
Audio/Video Outputs
Audio/Video outputs are typically used to connect an overhead monitor to an aftermarket stereo. This is the number of A/V outputs that the item has. These outputs are usually RCA Composite cables.

RCA Composite Outputs
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 a GREAT head unit

October 21, 2012

With all of the features this is the best unit for the money I have used in years. The signal processing makes my MP3's sound outstanding, though of course the CD is still better. The Bluetooth audio sounds better than a USB connection. Not that complicated to use, takes about 10 minutes to set it up. Has not failed me yet. The built in crossover is actually working great for me, three amps using only the built in crossover. Could use a little less bass on the front set but not so much that I need to add a crossover.

Sony MEX-BT3900U EXCELLENT

June 14, 2012

This stereo is an excellent value. I have it installed in a Tundra, and use all of its features. I purchased a few very tiny USB flash drives from Staples, and have tons of albums loaded. Also run XM through the front AUX input and use CDs full of MP3s. Stream Pandora from my phone and use the hands free. My state doesn't allow touching your phone while driving at all. Highly recommend.

Great!

May 24, 2012

I would like to recommend this one. It has all the functions I need, especially front USB, front aux in, Bluetooth. All the functions work well as they are supposed to do. Nothing to complain. Some comments said the white button on the front panel is too bright in the evening. I did not feel that. No problem at all for me. It has no SD/microSD card support. This is not very good, but I am using a USB reader to access my microSD card. So it is still ok. It only support CD. If it can support DVD, it will be great, but since I can use external USB, this is not very important. Conclusion: very very good. If it can support DVD and SD/microSD, it will be perfect.

Sony BT3900U

April 23, 2012

I've been running the Sony for about 6 months now and I couldn't be happier. This is my first BT stereo so I wouldn't call myself an expert but the audio streaming and BT calls work fantastic. I do wish I would have gotten the external mic as sometimes people say it sounds like I'm under water. I think its just because the stereo is far from me. Some have complained about the beeping when you turn your car off and I can't say it bothers me one bit. I don't even hear it anymore. Lots of power for the money!!!

What a deal!

April 12, 2012

Bought one of these about 6 months ago and installed quickly and easily in our old Saturn SL2, where it's also married to a Sirius tuner and Sony adapter. Worked so well that I've installed a second unit in another car and totally love it - except for occasional Bluetooth issues. Occasionally it locks up the phone's Bluetooth when streaming audio. Music simply stops playing and the phone needs to be powered down and restarted. Once, I needed to pull the phone's battery to reset. Another is that Bluetooth seems to always automatically connect to the phone functionality, but I usually have to stop and restart the Bluetooth transmission on the phone end to be recognized for audio play - this is no big deal. I don't know if this is the LG Optimus phone or player. All in all, I'm thrilled with the purchase - features abound, strong tuner and great sound. When coupled with the remote mic, telephone conversation is so good that most callers won't know that it's hands-free.

I really like this unit!

April 2, 2012

Pros: Quality of music is excellent, Versatile, Once paired to a device, It will always search for it as soon as you turn on the ignition. Examples like GPS unit and my cell phone using an android Atrix. It will also find whatever music I have on my phone and play it. I also purchased an optional microphone for it. It will automatically connect me to whatever phone call I may have. It shuts the volume off on the radio automatically. Cons: I have had this unit six months. I have yet to figure out everything it does. It's a bit complicated to use Due to the fact that the labels for each of the buttons are labeled so tiny you can't really see them. It would be handy here if the labels were Lighted. Mind you I'm an old fart! Not sure on how long it will last, as it's a throwaway society nowadays and most everything electronically seems to Die early. If it lasts as long as the car I'll be happy. All in all, I really love this unit!

Good product

March 11, 2012

I received the unit quickly and in good condition. I also ordered the seperate mic and was able to almost hide it in my headliner. The head unit works really nice and was easy to program all the PH stuff into. Mic operation is good but not great (my Prius factory system is better). I also really like the eq section which made my system sound better than the old head. The only really negative thing I have to say about this deck is in regards to the annoying beeps you have to listen to every time the key is turned off. Every other unit I've looked at allowed you to turn off this "feature" but this one won't. The one bright white button is really out of place and is distracting but I have gotten somewhat used to it. Selecting specific music from the Ipod connection is complicated and using the genre selection portion just doesn't work from what I have found.

March 6, 2012

Everything accept for a few flaws. Freezes up when someone calls me and Bluetooth is connected, and also if its not on tuner you wont be shown the time. Other than that its ok. I wish i could be heard better when making a call too. Also its very NOT user friendly when it comes to adjusting your equalizer, like bass and trebble etc.

Great sound quality

February 19, 2012

Like all Sony products, this unit produces great sound quality, better than the previous "premium audio system" on my Ford Escape 2003 Limited. My kid also loves the remote control. There are only some less than ideal features that I like to mention. When you turn on the RDS system, the tuner shows the additional info of the songs being played on the radio, but the clock will not show up. The white button light is quite bright in the night and unfortunately it can't be controlled by the car's instrument panel dim switch. I just put a piece of duct tape on the white button and it feels much better.

Great Deck

November 14, 2011

This is the second MEX-BT2900U I've bought from Sonic & Sony. The first went into my daughters car, so she wouldn't be as tempted to break the law on cell phone usage - the second for myself as my old deck didn't have BT phone options. It works great - I get in the car and the phone sync'd - then its easy to answer and talk using the sound system already in the car. Muisc from my phone also sounds great!! Really Happy with the purchase.

All Good

September 24, 2011

I purchased this unit because it had all the key features in one convenient package: Bluetooth with phonebook access, front USB port, built-in microphone, decent audio quality. Installation was straightforward. The sound is standard Sony quality (good for the price). The bluetooth works flawlessly. We are able to stream music and phone calls from our phones with ease. The built-in microphone works great! Sony must have good background noise cancelling built-in. People on the other end of the conversation hear me perfectly and can't even tell that they're on speaker phone in a car. My only complaint is Sony's silly default "Demo Mode" (designed for in-store displays) where all the lights flash and text scrolls across the display until you figure how to navigate into the menu and shut that mode down forever. Once you do, the display and controls are certainly more elegant.
