Mounting Dimensions

Tracker with GPS Technology

No lock is 100-percent effective at preventing theft. Instead, protect your investment by knowing where your vehicle or equipment is at all times. This small GPS tracking device lets you use the Linxup tracking service (not included) to discreetly track the location of your motorcycle, ATV, UTV, RV, trailer, car, boat, golf cart, farm equipment, pallet, cargo box, or basically any other item that it can be mounted on. You can also purchase several Linxup devices and track a fleet of trailers, trucks, rental vehicles, or security vehicles for your business.

The GPS battery in this device lasts up to 3 months without needing to be recharged, which makes it possible to track an item that has no power source. When the battery gets low, simply remove the device and connect the attached wiring harness to a power source.


The compact case on this GPS device can be wedged under your seat or into a tight spot that is hidden from view. The mounting holes allow you to attach this device onto your vehicle's frame, under your hood, behind the steering column, or onto a secure spot on your equipment.

Simple Wiring for Powered Assets

If you are using this device on a vehicle, boat, trailer, or other asset that runs on a 12-volt system, then you can easily connect the integrated wiring harness for power. Just mount the device in a place that makes it simple to run the power wire to your vehicle's battery or to your vehicle's ignition. The red and white wires on this device will either connect to the positive post on your battery or to the ignition wire. The black ground wire will then need to be attached to a bare spot on your vehicle's frame that is free from any rust or paint.

Rechargeable Battery for Non-Powered Assets

If you are installing the Linxup device on a non-powered asset, then you will want to install it with a fully charged battery. Simply click on the drop pin in Google Maps to monitor how much power the battery has left. A fully charged battery will last up to 3 months. To recharge the battery, remove the GPS device and connect the attached wiring harness to a 12-volt power source. The red and white wires can connect to the positive post on a 12V battery. The black ground wire will then need to be attached to bare metal that is free from any rust or paint.

Setting Up a Linxup Account

Once you install the GPS device, you'll be ready to choose and set up the Linxup service plan that works for you. When you purchase a service plan, you can download the Linxup mobile app on your phone or tablet. The mobile app is compatible with iOS and Android, and it is free to download from iTunes and Google Play. If you plan to purchase the 1-year service contract, check out part number 300-AT3-S, which is this same asset tracker paired with a 1-year Linxup plan.

Linxup 4G Tracking Service

Once you purchase a Linxup service plan, the Linxup online account and mobile app will show you a map view of your vehicle or equipment on your smartphone, tablet, or computer. The app will also send you alerts if the vehicle is moving. As a result, you can have peace of mind, knowing that your equipment can be found if it does get stolen. The tracking service runs on a 4G network for reliable transmission.

The Linxup app also makes it easier to manage your business. You can view multiple devices at the same time so that you always know where people are when you need them. And you can log data to see the amount of time your fleet spends traveling or on job sites. If you have a business fleet, you can track the time spent on each job to make invoicing customers easier.

Easy Tracking

Map View

The Linxup GPS device appears as a drop pin on Google Maps. This position will be accurate within 15' of the actual location of your vehicle or equipment. You can click on the drop pin to see how much battery power the GPS device has left, its current address, and the direction it is moving. The device's location is updated once per day when it is not moving. While in motion, the device will automatically accelerate the updates to every 10 minutes.

Google Maps gives you real-time traffic reports so that you can generate the quickest routes. You'll be able to dispatch the closest vehicle from your fleet to reach your customer faster, and provide an accurate ETA. In the map view, you can also add detailed information and notes about each vehicle or asset, including the serial number, license plate number, or vehicle identification number for quick reference in case you need to report your asset stolen.

Geofence to Better Manage Location of Asset


You can set up a geofence, or virtual perimeter, around either your asset or a specified location. You decide who will receive the text or email alert if your asset crosses the perimeter, and you determine what type of breach will activate the alert. For example, you can be alerted if your vehicle enters a perimeter, exits a perimeter, or both. When a breach occurs, the date, time, and location of the tracking device will be timestamped and recorded. This information can also be used to clock an employee in and out from a job site.

You can customize the shape of your fence to reach all corners of a specific location, or you can set landmarks and frequently visited locations on your map. Several fences can be set up in different locations and viewed at the same time to manage your business or fleet. Each customer location can be set up as a landmark, which can help you choose the most efficient route for the day. The time spent at each landmark will be logged, which makes invoicing easy.

Non-Authorized Hours and Tampering Notifications

Get an alert if your vehicle is moving during non-authorized times, or if someone is tampering with the GPS device. Simply set up a time range that is not authorized for movement, such as after business hours or in between scheduled routes. An email or text notification will be sent if the vehicle begins to move during your preset unauthorized time frame. You can also set up notifications to get an alert immediately if someone is tampering with the device.

Data Collection and Logging

History Reports

Each trip generates a report that can be viewed by selecting a date range within the past 24 months. A trip begins when the ignition is turned on and ends when the ignition is turned off. When you select a date range to view a report of trips, a breadcrumb trail will show you each location your vehicle visited during each trip in the selected time frame. On this trail, you will also see a history of alerts including the length of time spent at each stop, total miles for each trip, and whether or not the trip was made during authorized hours. In a report of stops, all stops made by the vehicle will be displayed for the date range that you choose. The start time, stop time, location, and the amount of time spent at each stop are all logged.

Alerts and Notifications

Text Alerts

You are in charge of all email and text alerts, and you can customize them for different vehicles and groups. All alerts that are available in the web service can be sent by an email, a text, or both. You decide who gets the alert, and you can alter the alert sensitivity for each notification. For example, you can set immediate notifications for time-sensitive alerts, such as device tampering.

Maintenance History

Maintenance Alerts

Get notifications for routine maintenance that is due on your vehicle. Simply log the type of maintenance and the interval between services, and you will receive an alert when your next service is due. You can view a history of all maintenance and unexpected repairs that have been performed on your vehicle, or on a vehicle from your fleet, by selecting a date range and the vehicle that you wish to review.

Trailer got stolen in October. Alert Text notified me that my trailer might be on the move. IT WAS! tracked it to the first location where they tried to disable thew tracker by cutting the wiring to the tracker and hitting it with something busting the case. It stopped the real time tracking but the internal battery kept transmitting the location every 24 hours. Trailer was recovered by police with the major High Dollar items still inside. Allot was stolen, but the major stuff was recovered. Linxup replace the tracker at no cost to me. Highly recommend this product and the Linxup Company 601524

Ask the Experts about this Linxup Trailer GPS

  • Comparing Linxup GPS Tracking Devices and Compatible Phone Networks
    The Linxup GPS tracking device # 300-AT3 is just the device by itself. It does not come with the service. This would allow you to choose what type of service you want: month to month, yearly. The other one, # 300-AT3-S, is the device plus 1 year of 4G tracking service. It doesn't actually work with your phone. The Linxup uses 4G service just like an LTE phone does but they use it separately. You can use the service on your phone for tracking as well.

  • Is the Linxup GPS Tracking Device # 300-AT3 Waterproof
    The Linxup GPS Tracking Device # 300-AT3 is weatherproof but not waterproof meaning that you would not want to submerge it. Water splashing on it from time to time would be fine. If at all possible mount the unit as far forward on the trailer as you can. If you routinely have the entire trailer submerged though it could eventually short out the unit.
