A/V Input
A/V (Audio/Video) inputs allow the unit to playback external audio and/or video sources typically using common, composite RCA connections. For example, you could connect an external DVD player, XBox360 or other audio or video device if the unit has an audio and video input. 1 A/V Input refers to 1 set of audio and video inputs. Other inputs may be included on the unit and we recommend you read the product description to find what type the unit has.

Bluetooth Connectivity
Bluetooth® technology allows two or more electronic devices to communicate with each other wirelessly, such as using your cell phones "hands-free" or transmitting music to Bluetooth enabled receiver. If a unit is Bluetooth capable, it typically can allow you to connect to your Bluetooth cell phone to make and receive calls. Others can access your phone and address book too via Bluetooth. Other Bluetooth capable units offer even more services, such as live traffic information and map upgrades.

More uses of Bluetooth technology include transmitting music to a compatible receiver, printing wirelessly from a computer, and many other wireless uses. Please see the item description for more specific information regarding what features the unit includes.

Traffic Tuner
In-dash navigation units with satellite radio have the option for a traffic tuner, also called a Traffic Message Channel. A Traffic Message Channel (TMC) is used to deliver traffic and travel information directly to the driver. When the TMC is built-in a navigation unit, it can help direct the driver to take alternative routes when traffic is bad.
These are the different options for language. If you are looking for a specific language, please verify that the unit will be compatible with that language.
