GlobalSat BR-355N Serial GPS Receiver (Black), Made in Taiwan

Works great

Used it with my Uniden Marine VHF Radio. The serial plug did not work with my Uniden. It did come with instructions that detail what each wire in the serial plug was for. So it was not hard to splice and use the wires I needed for my Uniden Marine Radio. It has a magnet in the base and comes with a suction cup.It was affordable considering Uniden’s GPS sensor were twice the cost and not available because they’re discontinued.It looks identical to the discontinued UNIDEN Marine Radio

Make sure your radio supports 3rd party gps receiver.You can cut the end to connect the wires directly.The user manual shows which wire goes whereyou can get the user manual from their website.

This GPS receiver is working plug and play with my SDS100, in addition you will need to buy separately the mini usb to serial cable directly from the Uniden oficial website 👍🏼

The GPS do not work with the uniden sds 100 scanner.

Don't know why I waited so long to get a GPS receiver for my uniden SDS 100 scanner. It's plug and Play, just plug it in, and it automatically fetches nearby police and fire frequencies. Works perfectly.

Used with the Uniden cable (you can make your own if you prefer) with my Uniden SDS-100. Works perfectly.This works!! Don't be concerned that it's not the "S4" version!

Did not work
