Product Summary
This is all you need to enable Location Based Scanning on your Uniden BCD-996T or BCT-15 TrunkTracker and easily listen to systems as you travel.

By programming latitude and longitude and range, these scanners will add and drop systems automatically based on your location so you're only listening to what's relevant to the area through which you're currently travelling! It's a fantastic feature of Uniden's newest base/mobile scanners and it's one you don't want to miss if you're using your scanner in your vehicle.

The GPS is simple to set-up. The unit has a magnetic base so you can just drop it on top of your hood, trunk or rooftop. It's tiny and will not disturb your car's appearance or be affected by the wind. Or, with a small piece of Velcro or double-stick tape or some other fastener (not supplied) you can mount the unit on your dashboard or windshild. There are three leads: One is a serial connection that goes directly to the back of the scanner; one goes to the tiny GPS receiver module; and the third supplies a fused positive/negative power lead which you can run right to your fuse block or to a cigarette lighter plug (available separately), or you could tap into the 12-volts going to the scanner.

You can also receive Location Based Alerts using the Universal GPS with Uniden adapter — Receive notifications you when you near an area you have programmed as a dangerous road, dangerous intersection, or a general point of interest.

(We recommend that you program the scanner with latitude-longitude and range with the Butel ARC software for the scanner. Butel provides a simple way to determine latitude and longitude in their software that takes seconds, rather than hours.)

More on How GPS Scanning Works

The GPS receiver feeds position data into the scanner. The scanner then reports this on its screen (in certain modes) but more importantly it uses the data to compare it against what the user has programmed. So if you program a county with a centerpoint latitude-longitude and a range of 20 miles, then the scanner knows from the GPS position report when it has entered within 20 miles of that centerpoint and that system automatically will enable (unlock). So when you drive you don't generally want to hear 25 miles away from you (you probably couldn't for the most part anyway). You just want to hear what's in your immediate vicinity. With GPS you can set this by range and as you approach your destination the areas that you left will become auto disabled and the areas you're approaching will automatically enable. Takes some time to understand how to program the lat-long-range correctly, but once done properly the feature works brilliantly.

Product Description
Uniden radios use data, supplied by Universal GPS unit, that lets the radio automatically unlock and lockout sites based on the geographical information you provide.

-Latitude (the center of the range or site)
-Longitude (center of the range or site)
-Range (the radius of a circle around the latitude and longitude coordinates selected from up to 50 miles form that center)

Also, when the radio is connected to the GPS, you can program specific location information such as Dangerous Xing, Dangerous Road, Points of Interest (POI), this will trigger an alert from the scanner. The scanner becomes an extension of the GPS device.
