To get started, you can enter your destination by address, city center, postcode, or intersection, and you can instruct the device to calculate directions based on a number of criteria, including quickest or shortest route, avoid toll roads, and required arrival time. If at any time you want to avoid a part of your route, you can tap the Find Alternative icon, and the GO 910 will plot a new course. You can view maps in 2D or 3D mode. A status bar at the bottom of the screen displays useful information, such as the next instruction, remaining distance, and estimated time of arrival. There are also two icons in the upper-right and upper-left corner that let you zoom in and out of maps.
The TomTom GO 910 is well stocked, with a comprehensive points-of-interest (POI) database that includes restaurants, gas stations, ATMs, parking garages, sports stadiums, and much, much more. You can search for these POI by proximity to your current location, along your route, or near a specific city. And while we like the fact that it gives you store names and separates restaurants by type, we noticed that some of the entries were outdated. For example, we searched for restaurants in the Marina/Cow Hollow neighborhood of San Francisco, and the GO 910 came back with a couple of restaurants that we knew were no longer there. Not a big deal in this scenario, but we can see where this would be a problem if you're in dire need of gas and a service station isn't where the GO 910 said it would be.
Now, we get into some of the TomTom GO 910's more advanced features. First, if you have a compatible Bluetooth cell phone, you can pair it with the GO to make hands-free calls. For incoming calls, you can either use the touch screen to accept or reject calls or turn on Auto-Answer in the Phone preferences menu to have the device automatically pick up after a certain time.
In addition to making calls, you can use the Bluetooth connection to access TomTom's Plus services, which include real-time traffic information, weather reports, and the location of safety cameras. There's also a cool feature called Buddies, which lets you see the location of any friends or family members who also have a TomTom unit. Just be aware that accessing these services means you're using the minutes from your cell phone's service plan, so use them accordingly. The other downside to this feature is that the list of compatible phones is pretty weak at this point. To see if your phone is supported, check out TomTom's Web site.
Finally, the TomTom GO 910 can also entertain. A built-in MP3 player lets you listen to your favorite MP3s or Audible audiobooks, and it also displays photos (JPEG and BMP formats). There are 12GB of user-accessible memory for storing these files, and you can easily transfer them to the device using the included TomTom Home software. And if all that weren't enough, the GO 910 offers full iPod compatibility.
Powered by a 400MHz processor and a SiRF Star 3 GPS chipset, the TomTom GO 910 offered solid performance. When we first fired up the GO 910, it took the unit about 2 minutes to acquire our position, and subsequent starts were much faster. The device accurately tracked our position as we drove around San Francisco, although like most GPS units, it did lose its satellite fix when we drove through an area populated with tall buildings.
Route calculations were quick, and directions were on the money; the TomTom GO 910 also did a good job of creating a new route when we purposely missed a turn. The speaker system did an admirable job with voice directions, and though volume was loud enough, the audio quality of MP3 playback wasn't the greatest, as songs sounded tinny and harsh. The GO 910's internal lithium-ion battery is rated for 4 hours.
