Garmin Zumo 390LM Motorcycle GPS Review

Garmin Zumo 390LM Pic 2The Garmin Zumo 390LM is yet another addition to Garmin’s long running Zumo line for motorcycles.  The Garmin Zumo line first came out in 2006 and continues to be a popular line in North America.


These 4.3″ screen size GPS systems are made for motorcycle use.  Unlike a car GPS, these are weatherproof and rated to IPX7 which means it withstands incidental exposure to water of up to 1 meter for up to 30 minutes.  So don’t attach these to a submarine.

The Garmin Zumo 390LM has a glove sensitive display which means that you don’t have to take your gloves off to interface with the display.  Lastly, they are made somewhat more rugged than car GPS units.

An interesting added feature is the ability to check your tire pressure using the optional Garmin Tire Pressure Monitor Sensor.  This is an additional accessory that can be added which is basically a smart air valve cap that speaks to the GPS.  This is a very useful feature that makes the Garmin Zumo line of GPS units somewhat unique.


The Garmin Zumo 390LM provides lifetime map updates at no charge.  Updates are done using the cable provided while attached to your home computer.

Like most of Garmin’s higher end car GPS devices, the Garmin Zumo 390Lm includes a feature called Lane Assist.  This feature comes into play when approaching junctions and interchanges.  The Zumo 390LM provides a brightly colored arrow to help you choose the proper lane for your next turn or exit.

The GPS includes Bluetooth integration so that you can hear the directions through a Bluetooth enabled helmet.

Bluetooth is an integral feature if you have any hope of hearing GPS commands.  The Garmin Zumo 390LM has a Bluetooth interface to your phone or Bluetooth enabled helmet.  You can use this feature to hear the directions and street names.  The feature also supports interfacing with your smartphone.  You can also use the Bluetooth feature to ask for points of interest, like gas or food.

The Garmin Zumo 390LM does not include the entertainment integration found in the more expensive Garmin Zumo 590LM.  So for example, you can’t use Pandora nor play MP3.

Fun and Different

Here are a few more interesting features.  There is a built-in trip computer with compass and speed limit display. There is also a digital fuel gauge that will let the rider know when it’s approaching the time to fuel up.  You can also integrate this GPS with the Garmin VIRB action camera.


The Garmin Zumo 390LM includes both a motorcycle and car mount which is a nice touch.  No reason why you can’t use these in a car as well as a motorcycle.  Saves some money in that you don’t need a second GPS for your car.  The car cradle has the standard 17mm socket on the back so a lot of the mounts that are available for a Garmin Nuvi that have a 17mm ball on the end will fit the car cradle for a Zumo 390LM.

We like the Arkon Suction Cup Mount for Garmin Nuvi as a suitable replacement that’s a notch above the Garmin entry and fits the cradle real well.  Don’t worry about it saying Nuvi, these fit the Zumo 390LM car cradle as it has a 17mm socket the same way that the Nuvi does.  There’s a vacuum lock on the mount to make sure it sticks firmly, just be sure to clean the windshield with the included wipe before use.  It also includes a dash disk if you would like to use it there instead of the windshield.


The Garmin Zumo 390LM is another good entry from Garmin for motorcycle use.  Compared to the Garmin Zumo 590LM, this is a more basic GPS.  The Zumo 590LM has better smartphone integration and MP3 abilities.  You will typically find the Garmin Zumo 390LM at a lower price than the 590LM.  It all depends upon if you’re ok with the smaller size and lack of smartphone integration.
