Hi, I have the Uniden BCD436HP Scanner and just got the Uniden GPSK BC-SGPS to scan with GPS while I travel. It’s not evening registering the gps as “gps” isn’t popping up in the bottom of the screen once connected. Everything is connected properly as I have the scanner connected to a cigarette adapter via usb powering the device and the GPS cable connected directly from the scanner to the converter. Any ideas why it’s not working? Could really use some help!
