I'm not so sure of that. The SDS200 uses a totally different type cable than any of the GPS capable Uniden scanners. It's a "one piece" accessory that plugs into an RJ-45 port on the back side. Unlike the GPS used for the SDS100, the x36HP series, and the other`scanners that can be attached to a GPS, there is no separate power cable for the puck. I have not seen a cable that would convert the GPS module used for the 536HP to match the SDS200. I suppose if you knew the correct pin outd for the SDS200, you could fabricate something to work, but nothing that is currently available pre-made.
I have written a guide for the new Uniden Universal GPS Receiver (BC-SGPS) for the Uniden scanners. This is not a Uniden guide but my own creation. It explaines the various parts and how to connect to the various scanners it supports. Enjoy!
