SDS100/SDS200: GPS question, led not coming on, GPS not being detected

[CHHTX]

I have an SDS100 and a GPS that is model BR-355 that I've had for a couple of years. I haven't tried using the GPS in many years and I'm wondering if I'm doing something incorrect.

Issue1: When I attach the GPS to my SDS100 (using the cable splitter {link here} that I know I've successfully used before, the little "GPS" indicator does not come up on the SDS screen. iirc, you must go "Menu>Set your location>Set up GPS>Set Serial Port>" then I think I remember the bps must be set to 9600.

Issue2: I believe the bigger issue the little red LED is not turning on the GPS puck itself. Shouldnt that LED be coming on if I have the baud set up and everything plugged in?

Baud rate is not correct. Google it up.

Your issue #2 should actually be your Issue #1. Device won't work with out power. Fix that, then see if the other issue resolves itself.

(I just remembered that i'm not using a BR-355, the LED comes on my GPS reciever only when power is applied. Can't speak authoritatively for the device the OP has)

yeah, I've wondered abou that! From my old notes, I had down to set it with 9600. I change it to 4800 though and still no luck. It looks like it might be the power first though. thanks for catching that

Thanks for the input. I think its not getting power for some reason. According to the manual here

from the easy to read manual
You can connect the scanner to a NMEA compatible GPS device
For the SDS100, use the micro USB jack (USB1) under the flap to connect to the scanner.
You should select a baud rate of (4800 bps) for the serial port in the Set Your Location menu.

that's interesting that it says that even though I think it would depend on which GPS module you're using. The older GPS models use 4800 and IIRC the newer GPS modules use 9600

Something useful for people later. I learned today that even before you plug the GPS in to the scanner, you should get a red LED on the GPS. I was trying to use a BR-355. The guy in the video made his own cable but its also available for as little as $30 on amazon. Here's a helpful video I found.

I have determined that my GPS is not powering up. At this point, I'm not sure if its my cable or the GPS. I went ahead and ordered the Uniden BC-SGPS for $80 from amazon since it will run on either the SDS 100 or the 200.

I'm glad you got to this point, my GPS puck is powered off its own USB power source, and only sends data to the SDS. If I don't see the power LED on the puck on - I know for a fact that it's either unplugged or otherwise compromised.
