Overhead Monitor Specifications

Screen Type
The type of technology used to produce the screen images. LCD, DLP, Plasma, LCoS, and CRT are the most common. 2 newer technologies include LED and OLED which use light-emitting diodes (LEDs) as a backlight, as opposed to conventional LCD TVs, which use cold-cathode fluorescent lamps (CCFL) for a backlight.
Screen Size
This is the size of the monitor on the unit. It is measured diagonally and in inches. The bigger the number the larger the screen.
Resolution (pixels)
A display's pixel resolution defines its ability to resolve fine details. Digital TVs and projectors measure screen resolution in pixels. The higher the resolution, the more detailed the picture will be.
1280 x 800 
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.
If a unit is touchscreen capable, you can control a majority of it's functions by touching the screen.
HDMI Input
High-Definition Multimedia Interface (HDMI) is a compact audio/video connector interface for transmitting uncompressed digital streams. HDMI output means that the player has the capability to output this type of data. An HDMI input will allow you to connect game consoles, Bluray players, smart phones and other high definition devices (if compatible)
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.

1 Set of Rear RCA A/V Inputs
Audio Output
An audio output on small devices such as this is typically a 3.5mm mini-jack ("headphone" style) that allows you to connect the unit to headphones so you can listen to music and use the unit as a portable media player. You can also connect the audio output to a car stereo that has an "Aux Input".
1 Set of Rear RCA A/V Outputs
Built-in IR Transmitter
An IR transmitter allows the unit to transmit audio signal to IR wireless headphones.
Built-in DVD Player
Indicates whether or not the unit features a built-in DVD player.
Headphone Input
Indicates the availability of wired headphone jacks featured on the unit.
OSD (On Screen Display)
Indicates that the unit has menus and features that display on the screen. Typically, on-screen menus allow users to adjust audio and video settings easier.
OSD Languages
Indicates the languages featured in the OSD (On Screen Display).

"Multilingual" includes three of the major European languages (English/Spanish/French) plus many others such as German, Italian, and more.

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.
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.
Swivel Mount
Swivel mount allows the screen to be rotated or turned to a much more comfortable viewing position.
Primary Color
This is the main color of the item.

Great picture for the price

May 17, 2015

I installed two of these in our sequoia. Easy to install and a great picture. The headphone do have a short range but they work very good.

For the BV 12.1, Screen size, resolution, price and warranty compared better than the Power Acoustik options I was considering.
Dan C on Aug 29, 2016
The three year warranty and the headphones. It was missing a couple features from the one I was comparing it to... but we did not use those in our last model anyway! And they usually seem to break in year 2... so I feel a little better that this one is covered!
Debra T on Jun 13, 2016
does this have to be installed by any one special or can car owen install?
redgigi on Sep 30, 2015
Best Answer: I have done professional A/V installations for over 30 years and I would say that unless you are VERY familiar with vehicle electrical systems( Connecting to the wrong wires can cause massive/expensive computer problems), have a good selection of specialized installation tools and test equipment/access to vehicle wiring diagrams and have comfortably installed one of these before. Then I would consider getting someone that meets all those requirements. And even then, I would as a lot of questions and seek reccommendations. Make sure it is directly braced to the roof brace, not just supported by the headliner(To heavy)
