Installing a GPS-enabled media device is very simple.
In the case of the Digital Audio Machine, the device can be placed anywhere there is room as long as there is access to power and the audio cabling. The device can take the place of an existing CD or cassette player or you can use an audio switch to select one or the other, depending on the operator’s requirements.
In the case of the Digital Video Machine, the device needs to have access to power and the audio/video cabling. Most times it can easily take the place of a DVD player or VCR.
Both devices come with a GPS “mouse” or antenna that is used to triangulate the vehicle’s location. This antenna needs to have line-of-sight access to the sky. Many of them have magnetic mounts so they can stick on a piece of metal. Then, run the cabling to the port on the Digital Audio Machine or Digital Video Machine.
Both devices run off standard vehicle power so you do not need a DC-to-AC power inverter to supply the electricity. If there is a visual signage system, connect the RS-232 serial port on the Digital Audio Machine or Digital Video Machine, to the signage system.
A quick note on device location: the sounds/video are stored on a CompactFlash card in the front of the unit, so you may want to allow easy access to the card if you are going to change out media frequently. If you plan to update content via Ethernet, you will need Internet access and an available Ethernet port on the vehicle. While this may sound like the best option, replacing the CompactFlash card is easy and it contains all of the media and programming necessary to make your system run.
