The Good The TomTom One 140 S features advanced features such as lane guidance, downloadable fuel prices, and user-updated maps from TomTom Map Share. Text-to-speech enhances the device's safety.

The Bad The smallish screen size tends to crowd the buttons on the address entry screen, which makes inputting text difficult. Routing from a moving vehicle is considerably slower than from a stationary one.

The Bottom Line The TomTom One 140 S benefits greatly from feature trickle-down, bringing high-end features to an entry-level model without much price bloat.

The TomTom One 140 S builds on TomTom's successful One series of entry-level portable navigation devices (PNDs), with the addition of features that were once the hallmarks of TomTom's top-of-the-line models.

The diminutive PND gains advanced lane guidance, which details complex freeway interchanges for easier navigation, as well as downloadable (via subscription) daily gas prices to help users find the lowest-priced fuel in the area. IQ Routes and TomTom Map Share work together to constantly update the map data and route mapping algorithm, so, in theory, the device should get better with time.

Design
While the details have changed slightly, the One 140 S doesn't stray too far from the tried-and-true PND formula.

The entire front of the devices is occupied by a 3.5-inch QVGA touch screen, while the back is dominated by a large and loud 2-inch speaker. The only physical control to be found is the power button on the unit's top edge. The only I/O port is the Mini-USB port on the bottom edge that also serves as the connection for the included 12-volt car charger.

Unlike the its primary competitor, the Garmin Nuvi, the One 140 S does not feature an SD or MicroSD card slot, so you 're stuck with the device's 2GB of onboard storage (most of which is occupied by map and voice data).

TomTom's clever EasyPort mount integrates the One's cradle into the back of the unit. To attach the unit to your windshield, simply flip out the suction cup, place the device on the windshield, and twist the locking ring a quarter turn. The twist-lock suction cup doesn't feel as secure as the Garmin's lever-actuated suction cup, but the TomTom's rotating mount offers a bit more flexibility with mounting angles. The integrated cradle adds considerable bulk to the One's profile, but also makes it easy to take the whole kit with your when you leave your vehicle, which is great for security.

Also included with the One 140 S are a 12-volt car charger, a USB connection cable, and an adhesive disk for attaching the One to your vehicle's dashboard, if windshield mounting is not permissible.

Features
The newest feature to reach the TomTom One is advanced lane guidance, which shows detailed illustrations of complex freeway interchanges, complete with lane information. Arrows overlaid on the illustration notify drivers of what lanes will keep them on the chosen route.

Text-to-speech functionality allows the One 140 S to announce street and POI names aloud. Users who don't need spoken names can step down to the One 140 (sans "S") and save a few bucks on the MSRP. The unit comes bundled with 14 English, French, and Spanish voices. More voices can be downloaded from the Web for a fee, including celebrity voices. (Our personal favorites are Mr. T and John Cleese!)

Using the free TomTom Map Share service allows users to make corrections to street names, directions, road speeds, POIs, etc. and upload those changes to be approved by and shared with other TomTom Map Share users. If you don't trust the hive mind, you can choose to opt out of this service and only receive official TomTom updates.
