The One 125 offers various routing options, including quickest or shortest route, with or without toll roads, and so forth. As we mentioned earlier, there are also pedestrian and bicycle modes. Once you've entered your trip, you can review the itinerary on the map, as text-based directions, or get a running demo. If at any time you want to avoid a part of your route, you can tap the "Find Alternative" icon to get new directions. The system also supports automatic route recalculations and multidestination trips.
The PND's points-of-interest database includes all the major categories, including ATMs, gas stations, and lodging. Sadly, you can't search for restaurants by cuisine type. If you have more specialized interests, the catalog also features entries for beaches, campgrounds, cultural centers, and more. There are various ways to plot to POI: you can search for them along your route, near your destination, or near home.
You can view maps in 2D or 3D mode. A status bar at the bottom of the screen displays useful information, such as the distance and direction of your next turn, remaining distance, and estimated time of arrival. If you crave more or less information, you can customize what is shown on the status bar under the Preferences menu. Tapping the left half of the status bar (where your next instruction is displayed) will repeat the voice directions and give you access to the volume control. There are also two icons in the upper-right and upper-left corners that let you zoom in and out of maps.
In addition to the visual cues, the TomTom One 125 offers voice-guided turn-by-turn directions, but unfortunately, unlike the One 130S, you don't get text-to-speech functionality. This means you'll hear more generic instructions, such as "Turn left in 100 feet" instead of specific street names. Even though the One 125 is a basic system, we still would have liked to have seen the inclusion of text-to-speech functionality.
There are some additional goodies. Like the most recent TomTom GPS, the One 125 includes the "Help Me!" safety feature, which gives you access to a number of tools and information in case of an emergency. For example, there's a "Where am I?" function that will give you your current location, longitude and latitude, and nearest intersections. In addition, you can find the nearest police station, hospital, car repair shop, and other services with just a tap of the screen. It's very handy and gives you a bit of peace of mind, especially if you are in unfamiliar territory.
We tested the TomTom One 125 in San Francisco and Los Angeles. From a cold start, it took about two minutes for the GPS to get a fix on our location under partly cloudy skies, while subsequent starts were much faster. As we drove around San Francisco, the unit did a good job of tracking our location and keeping up with our movement. It was also able to keep a GPS fix as we drove through the Financial District, where tall buildings often block a clear view of the sky.
We used the GPS on two trips: one from San Francisco to Los Angeles and the other from the Marina District of San Francisco to CNET's downtown headquarters. We entered our start and end points on the first journey, and the One 125 returned with a route in less than a minute. Though the route was pretty straightforward, the PND smoothly guided us through several highway interchanges, especially in Los Angeles as we neared our destination.
We experienced similarly positive results on the second trip. The TomTom One 125 offered accurate directions and, unlike the TomTom One 130S, we were able to hear the voice-guided instructions with no problem. They were loud and clear, but again, we wish it had text-to-speech functionality. Finally, we missed several turns along the way to test the route recalculation rate and the GPS was able to get us back on track quickly.
