Trying to stay ahead of do-it-all smartphones, less than a year after Editor Tuttle’s evaluation of the zumo 350LM GPS (Rider, February 2013) Garmin has released a new model to replace it. The zumo 390LM has all of the features of the 350LM, plus three new ones—Bluetooth connectivity for mobile phones, “Curvy Roads” navigation and tire-pressure monitoring—for the same retail price ($699.95).
Like the 350LM, the 390LM has a rugged hard rubber case that is fuel- and UV-resistant and can be submersed in water up to 1 meter deep (botched river crossing?). It has a 4.3-inch color touchscreen that is glove friendly, and on the back there’s a micro SD card slot and connections for an external headset and mini USB cable, all protected by rubber covers, as well as two small contacts to draw power from the cradle when the DC cable is connected to the motorcycle’s battery. The 390LM is preloaded with maps for North America, and it comes with everything you need to mount the GPS to your motorcycle or in your car, plus an accessory charger and a USB cable. Connect the 390LM to a computer to download updates for the firmware and lifetime maps (that’s what “LM” stands for), or upload routes from Garmin’s free BaseCamp trip-planning software.
Pairing the 390LM via Bluetooth with my iPhone and Cardo scala rider Q3 headset allowed me to listen to turn-by-turn directions through my helmet’s speakers (the 390LM also has a built-in speaker) as well as use the GPS touchscreen to search the unit’s database of businesses or my phone’s contacts, and to initiate or receive phone calls.
Curvy Roads is a new option in the Calculation Mode portion of the navigation menu, in addition to Faster Time, Shorter Distance and Off Road. After entering a desired destination, the routing algorithm calculates one or more possible routes that maximize the number of curves along the way. Combining it with the “Avoid Highways” function all but guarantees a backroad route, but the algorithm limits how far out of the way it will send you in pursuit of curves. Curvy Roads is helpful but limited. It does not identify the best or curviest sections of the route, nor does it allow you to simply navigate to the nearest twisty road. I’d love to see Garmin include a database of scenic routes/byways as well as famous and lesser-known motorcycle roads.
The new Tire Pressure Monitor System (TPMS) requires two sensors, which are sold separately ($69.99 each) and are compatible with metal valve stems only. After pairing the sensors with the 390LM and installing them on the valve stems, you set the recommended tire pressure and desired low-pressure threshold. If pressure in either tire falls below the threshold, a warning message is displayed on the screen. Claimed battery life for the sensors is 300 hours, and they switch to sleep mode after the 390LM is turned off; wheel movement reactivates them. Easy to use and undeniably useful.
With the zumo 390LM, Garmin has improved upon what was already a feature-rich, user-friendly motorcycle GPS. The cost of $839.93 including the accessory TPM sensors isn’t cheap, but if your style of touring includes long distances to remote places, it’s a worthy investment.
