Although Garmin claims “up to 4 hours” of battery life, it achieved only about 3 hours in my real-world testing, similar to the TomTom Go 720. The 255W has a built-in lithium-ion battery. The touchscreen was quite responsive, although I typed more quickly than the 255W’s audio feedback could keep up with, a trivial annoyance. It’s a 4.3-inch widescreen display showing 480 by 272 pixels, and it’s quite readable in bright sunlight, which hasn’t universally been true with other units. With so few physical controls, you use the 255W’s color touchscreen for everything. Instead it merely tells you to disconnect from the computer. WebUpdater was easy to use, although, as with the TomTom Home software, WebUpdater doesn’t tell you to eject the unit once it has finished updating

I did this successfully to update my unit’s firmware.

When connected via USB, you can also use Garmin’s downloadable WebUpdater software to install updates and, I presume, new maps, though my unit’s maps were up to date. Connecting it to my MacBook caused it to mount like any other external disk, and I was able to copy a 28K JPEG to the appropriate folder and set it as the startup image. The only other thing on the case is a USB jack that you use to connect the 255W to the car power charger or to a computer (where it charges as well). In theory, you can set any image to appear at startup, but a 2.7 MB photo flummoxed it entirely. If an SD card contains JPEG images, the 255W can display them via its picture viewer application, though it’s sluggish with high-megapixel images.

This slider worked exactly as I expected, unlike the TomTom Go 720’s power switch, which constantly irritated me (see “ Back in the Saddle with the TomTom Go 720 GPS,” ).Īn SD card slot on the left edge offers the opportunity to add more maps (Garmin sent me a unit with maps of North America pre-loaded, along with an SD card that contained maps of Europe, since much of my testing took place in the UK). Cleverly, it slides to the left to turn the unit on or off, and latches to the right to lock the unit off (or if it’s on, to lock the screen). There’s only a single slider on the top-left of the case, used for turning the unit on and off. Simple Hardware - The elegance of the 255W begins with its hardware, although such simple designs are more common now than some years ago, when physical buttons overwhelmed the case. As a result, this unit ranks highly among the units I’ve used so far.

My latest test unit, Garmin’s $349.95 nuvi 255W, sits near the low end of the company’s product line but does a bang-up job of providing just the features necessary for a successful car navigation device, eschewing many inessential items on the feature checklists in favor of a lower price and simpler usage. And similarly, even though every GPS is essentially a tiny computer, giving the user the ability to customize nearly every option isn’t always desirable – geeks might like it, but many other people will be confused and simply stick with the defaults.
