Overview

The Garmin 010-01031-00 is a GTM 60 HD Digital Traffic Receiver and vehicle power cable that adds Digital 3D Traffic to compatible Garmin nüvi navigators while powering the unit from a 12-volt accessory socket.

It uses Garmin 3D Traffic and Digital Traffic delivered through the HD Radio broadcasting system to provide traffic alerts in North America, with updates that can arrive up to 10 times faster than traditional traffic receivers. Traffic alerts are subscription-free and ad-free for the useful life of the Garmin product, and traffic content is not available in all areas.

This is an on-road accessory rather than a marine navigation input, but it is useful for boaters who trailer or travel by vehicle to the marina and want traffic-aware routing on the way to the ramp, yard, or service shop.

Compatibility and fit

This traffic receiver and power cable is intended for select Garmin nüvi models that support the GTM 60, including units in the nüvi 2400 and 3400 series. Common compatible examples include nüvi 2455LT, 2455LMT, 2475LT, 2495LMT, 2555LT, 2555LMT, 2595LMT, 3450, 3450LM, and 3490LMT. If your navigator has traffic built into the device, it may not use a GTM cable, so match accessories to your exact model before ordering.

Installation and setup

Replace the standard vehicle power cable on your navigator with the GTM 60 cable, then plug the adapter into a 12-volt accessory socket. After the GPS unit has satellite reception and the cable is receiving traffic signals, traffic data begins to populate and the subscription activates automatically.

For the first start-up in a new area, allow up to five minutes for traffic acquisition. For best reception, keep the cable routed away from heavy metal obstructions and avoid coiling excess length tightly around other power wiring.

Use cases on board

This is a good match for boat owners who rely on a compatible Garmin nüvi in a tow vehicle, RV, or runabout car for trips to launches and marinas where traffic delays can throw off tides, reservations, or service appointments. It is also useful for crews who shuttle between the dock and home base and want live traffic awareness during the drive.

Maintenance and care

Keep the connectors clean and dry, and avoid placing the cable where it will sit in standing water or take direct spray. If it is used around a marine environment, wipe down the plug ends after humid or salty exposure and route the cable so it does not chafe on sharp edges or pinch points.
