The one I received a few months back only came with a single cable (which it looks to be about 6-7 feet in length (part of it is installed in my SUV, so I can't measure it accurately but the telecom industry uses 7 foot as a standard). The cable is a 4-wire (2-pair) RJ-14 cable, but uses the same size connector as a standard phone cable - eons ago you could buy such a cable at Radio Shack, before they went under, so they were at one time fairly common. (
Here's a 14 foot version on Amazon) but I don't know the range limitations of this receiver.
Part of the answer to the question is it long enough is what type of scanner you're connecting it to.
- If it's an SDS200, that cable plugs straight into the back of the radio from the GPS module.
- For all other models, the GPS module connects to a converter box, which buys you some range.
The "converter" box has three connectors, one for the cable from the GPS module, the second for power, and the third for whichever of the three interface cables you need for your radio, each of those I would put at about 6 feet.
In my case, the cable from the GPS module is just long enough to go from the passenger side A-pillar on the dash, down along the trim and out underneath the passenger seat of my SUV. The converter box is there, with its power cable plugged into a switched multi-outlet that I also have under the passenger seat. The interface cable (another 6 foot) goes from the converter box into the center console, where it routes up to the cup holder where my SDS100 resides.
The nice thing about the USB cable for the SDS100 (and other compatible models) is it also provides power for the SDS100, so you're not stuck running on the device battery when in the vehicle.
