Here's the deal:

Order the "BMW Magic Box" from Nav-TV for $265 (plus sales tax in California and a reasonable shipping charge). When the small package arrives from Nav-TV, just follow the instructions.

You'll need the printed installation instructions from Nav-TV, a small screw driver and a few other basic tools for removing connectors and panels, your camcorder (for testing purposes unless you also purchased a back-up camera from Nav-TV) and a TV-tuner/AV controller with diversity antenna system (optional) that you can get on eBay for about $175.00 or less.

Starting in the trunk, carefully open the panels to the navigation system and remove the blue connector from the computer and plug it into the "box," then connect the blue connector from the "box" into the navigation computer.

After affixing the "box" to the trunk panel with its velcro strips, connect the small wiring harness from the "box" to the power inputs for the computer using the wiring harness provided, then connect the separate harness from the "box" to the backup light cable as illustrated on the instructions.

Connect the TV-tuner/AV controller into "Input 2" of the "box" with standard RCA cables and the power cord from the TV-tuner/AV controller into one of two 12V power outputs on the "box." Loosely connect the diversity antenna's to the TV-tuner/AV controller for now; you can more professionally afix them later.

Connect your camcorder (or the back-up rear view camera if you purchased it from Nav-TV) to "Input 1" on the "box," turn it on and point it to something in the garage. Start your BMW and put it in reverse (pressing the brake of course) and you should see what your camcorder sees on the navigation screen in reverse. Slide the gear shift back to park and the navigation screen should return to its normal display.

Now, tune the car's radio to one of the FM frequencies specified on the TV-tuner/AV controller instructions and turn on the TV-tuner/AV controller with its remote control. Using the remote, seek a local TV station. The navigation screen should change to TV and the sound should come through your FM radio. Put the car in reverse again, and the screen should display the (reversed) camcorder image again (and you can hear outside sounds as well if you want); put the car out of reverse and the navigation display should return to TV.

You now need to run the provided combined wiring harness from the "box" and the TV-tuner/AV switcher to the back seat area (up to 2 video outputs are available) and install a discrete switch under the armrest that switches the navigation display from its normal mode to video. Running this harness is probably the most labor intensive part of the installation.

Reverse view is automatically controlled for the navigation screen so no additional controls are needed for that and the 2 rear seat video outputs always display the video input, but not the navigation system screen data (unless you want to do some very creative wiring).

A small video camera can be installed near the license plate and connected to "Input 1" of the "box" where the camcorder was connected for testing. If you do not install the backup camera, no switching of the screen will take place.

Next you can connect up to two 7" wide screens (optional) to the terminated cable harness for the back seat passengers and plug in a DVD and/or MP4 player into the TV-tuner/AV controller in the trunk.

For the technical, the "box" is a microprocessor (powered by an interconnecting cable to the navigation computer power input cable) that converts composite NTCS video into RGB outputs for the navigation screen. It also contains a relay that switches the navigation display from its normal mode to "Input 1" when a video signal is present (i.e., power is provided to the backup camera for reverse viewing) and reverses the screen image. When a signal is present from "Input 2" (i.e., the TV-tuner/AV controller) and the "discrete" switch is on, the navigation screen displays whatever is on that source; when the "discrete" switch is off, the normal navigation display is seen.

And you can fairly quickly disconnect the "box" and all its attachments and reconnect the original wiring just as it came from BMW if you need to.

The most difficult part of the install will be for Nav-TV to provide the part number for the "box"...

Moni? Nav-TV?? Are you here???
