5 Important Factors We Tested the Product On

So now we know the hardwired GPS tracker can track your vehicle and provide alerts about driving behavior, towing, and possible theft. But how well does the tracker deliver in terms of performance? Let us find out.

1. Design


Hardwired trackers tend to be bigger than portable trackers. But they can still be compact enough to fit under your car’s dashboard.

The MasTrack device has dimensions of 3.6 x 2.18 x 0.5 inches. It weighs around 2 ounces.

The device comes with three required and a couple of optional ones. The red, black, and white wires are required.

Connect the red wire to a 12 V constant power source. Connect the black wire to a solid chassis ground. Connect the white wire to a switched 12 V source; this monitors the vehicle’s engine on and off state.

You can optionally connect the yellow wire to a positive input source. It will alert you about a voltage change in the connection.

There are two LED lights on the device. The green is for the GPS signal, and the blue is for the cell signal.

It’s a decently-designed tracker that can be used with different vehicles.

2. Battery

Once you activate the device and connect the wires, as mentioned above, it will start working. It will draw power from the vehicle’s battery.

The best part about hardwired trackers is that they are a one-time installation product. You do not have to track the battery percentage and set reminders to charge the device.

MasTrack offers an optional backup battery for the tracker. You can connect the backup battery to the adapter on the wiring harness. The backup will keep the tracker running for up to an hour once disconnected from a power source. You will also receive a tampering alert at the same time.

The backup battery is a good addition to the hardwired GPS tracker.

3. Usability

The best place to install the tracker is under the front dashboard behind the instrument cluster or radio. Ensure the label side of the device is facing downwards, as the GPS antenna is on the opposite side.

You can activate the tracker on MasTrack’s website. As a new user, you first have to sign up. Existing users can log in to their accounts and add the new device to the same account.

You will need the IMEI code of the device during the activation step. Also, decide on the service plan you would prefer. Activation can take about an hour.

The device comes with a 3-wire installation. Any professional who can install a car stereo or alarm should be able to help.

You can use the live tracking portal or download the MasTrack Live GPS app to track, customize alerts, and manage your device.

Using the portal and the app is pretty straightforward. But both mediums could do with some performance improvements.

4. Features

Geofence is a common feature that you can find in most trackers. You can customize an area that you deem safe. You will get an alert when the tracker leaves or enters these predefined areas. So you can know when your teen leaves school and reaches home.

You can set a speed threshold. When the vehicle crosses the speed limit, you will receive an alert. You can also get another type of speeding alert. It happens when the vehicle crosses a speed limit posted on a specific route.

You can get other aggressive driving alerts like harsh braking and rapid acceleration. The device includes a 3-D accelerometer that can detect a potential collision and alert you about the same.

You can know when the vehicle ignition was turned on and off. If the device loses power, you will be alerted. It could be a wiring issue or an indication that the device is tampered.

Overall, the tracker offers several value-adding features. But note most of these features are available in the mid and high-range service plans.

5. Performance


Depending on the service plan, the tracker can provide location information every 1 to 5 minutes.

You can track your vehicle on Google Maps. The tracking accuracy was decent at best.

The tracker needs a cellular network to transmit data back to MasTrack servers. So in the case of poor cell signal, you could notice a dip in tracker performance.

Also, the Google Maps version isn’t the latest, so accuracy takes a hit again.

The alerts showed expected performance. The best part being you can get unlimited email and text alerts. You can also access historical data right from when the device is active to the present.

Overall, the GPS tracker offers decent performance and could do with maps and accuracy improvements.

What Sets the MasTrack Hardwired GPS Tracker Apart from its Competitors?

You get the roadside assistance program if you opt for a 12-month premium service plan. The program has a value of around $400.

It offers towing, battery boost, fuel delivery, tire changes, lockout services, and winch/pull-out. You can use the program a total of four times a year.

A design feature that is worth mentioning is the optional green output wire. You can connect this wire to any desired system inside the vehicle. You can now control the system from a web interface.

Once the output feature is activated, the green wire acts as the ground and, in turn, activates the connected system. For example, you could cut off fuel or ignition.
