Marine VHF radio with Bluetooth and GPS

The Uniden UM725GBTBK is a fixed-mount marine VHF radio that covers all USA, Canada and International channels. It transmits at selectable 1-watt or 25-watt power and includes a built-in GPS receiver plus Bluetooth connectivity. A speaker microphone is supplied and the unit carries an IPX8 waterproof rating.

Boaters who need DSC distress and NMEA networking

This radio suits captains who want DSC distress send and receive, NOAA weather alerts and the ability to exchange GPS or DSC data over NMEA0183 and NMEA2000 connections. Bluetooth lets a paired smartphone send text messages over VHF frequencies to other equipped radios. Vessels that only require basic voice communication without data networking or smartphone integration may not need these features.

Largest LCD in class at 68 mm by 38 mm

The display measures 68 millimetres wide by 38 millimetres high, providing more visible information than other models in its category. This screen size is the key specification for operators who prioritise at-a-glance readability of channel, GPS and DSC data while underway.

Questions about this item

How do I wire the NMEA0183 and NMEA2000 connections when installing the UM725GBTBK?

Connect the NMEA0183 and NMEA2000 cables to the radio's dedicated ports so GPS and DSC data can be sent to or received from other onboard devices.

What ongoing maintenance does the UM725GBTBK require?

Rinse the unit with fresh water after saltwater exposure, check the speaker microphone seal for debris, and verify GPS acquisition before each trip.

What is the first limit reached during extended high-power transmissions?

The 25 watt transmit setting generates the most heat, so thermal protection will reduce power before the battery or antenna limits are reached.
