In-Dash Receiver Specifications
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.
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.
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.
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.
- RMS Power
- Signal-to-Noise Ratio
This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.
Audio / Video Inputs
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.
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.
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.
Some Car stereos are compatible with iPods and/or iPhones. If the headunit can connect to an iPod or iPhone via USB or iPod connection cable, these listed iPods are compatible. This list does not apply if the iPod is being connected through the 3.5mm mini-jack plug. Newer iPods are usually compatible if the appropriate adapters are purchased and used.
Any iPods/iPhones released after the release date of this product have not been checked by the manufacturer and/or Sonic Electronix for compatibility. We therefore cannot guarantee their compatibilities or incompatibilities, including, but not limited to: playback, video, charging, and response time.
