Quick take: The Uniden BC-SGPS supplies location data to compatible scanners so supported location-based scanning features can update as you travel. It does not improve radio reception.

What does the GPS receiver do?

It sends location information to a compatible scanner. When properly configured, location-based scanning can help select relevant nearby radio systems as you move between areas.

Which scanners can use it?

Compatible Uniden models include the SDS100, SDS200, BCD436HP, BCD536HP, and certain other GPS-capable models. Connections and setup vary. Check your model's instructions before ordering.

Do I need this for an SDS150?

The SDS150 has built-in GPS, so an external BC-SGPS receiver is not normally necessary.

Does GPS unlock encrypted traffic?

No. GPS provides location information. It cannot add unsupported radio formats or decode encrypted channels.

What's included?

The BC-SGPS GPS receiver with its supplied connection hardware. Confirm that the included adapters fit your scanner before ordering.
