GPS is Everything! for the Uniden Scanner.
The puck and cable was needed to complete the GPS capabilities of the Uniden SDS200 scanner. It was actually replacing an older stock puck. The repair was plug and play seamless. The difference of the SDS Scanners without the GPS is like watching a black and white television that you have get up to change channels. I drive 350 to 700 miles a day, and the GPS is an amazing and necessary item for traveling with the scanner.
