Editors' note: Parts of the Features section were taken from our review of the Navigon 7200T, since the two GPS units share a number of the same features.
Navigon's portable navigation devices (PNDs) haven't had the best track record when it comes to performance, but we thought the tide had changed with the Navigon 7200T, which offered a far better user experience than previous models had and boasted accurate directions. That's why we had high hopes for the Navigon 8100T, the company's most ambitious GPS to date. The 8100T not only features an extra-wide touch screen, but it also has something called Panorama View 3D, which brings 3D topographic-like maps to the viewing experience. In addition, you also get a number of other great navigation features, including text-to-speech functionality, voice commands, advanced lane guidance, and free real-time traffic for life. However, it's all overshadowed by the PND's subpar performance. The Navigon 8100T is frustrating to use given its sluggishness and bugs, and while the panorama view is cool, it doesn't bring any significant benefit. This is really a shame, given that the 8100T does its main job of navigation well, but if we're expected to pay $599.99 for the GPS, we want something that will deliver on all fronts.
The Navigon 8100T is a bit of a departure from the company's other portable navigation systems as far as its design. It sports a silver brushed-metal finish rather than the typical black plastic casing, giving the GPS a more sophisticated look and quality build to match its high-end feature list. The 8100T is slightly on the larger and heavier side, at 5.3 inches wide by 3.3. inches tall by 0.9 inch deep and 9.4 ounces, but there's a good reason for the bigger size.
The reason is that the 8100T features an extra-wide, 4.8-inch touch screen with a 16:9 aspect ratio. Most of today's GPS devices sport 4.3-inch displays, but Navigon added the extra screen real estate to complement the 8100T's Panorama View 3D, which we'll talk about in the Features section. In general, maps and text look clear and bright. You can choose between day and night map colors or set it to automatic so the system will switch it for you based on the time of day.
The 8100T's user interface is like other Navigon products: fairly easy to use, but not as intuitive or simple as a TomTom or Garmin. The onscreen keyboard is large enough that you should be able to input addresses without too many mispresses. That said, we're disappointed that there's still no QWERTY format option, but even more frustrating is the system's sluggishness, which affected the address-entry process. We'd input letters, but they wouldn't appear for a couple of seconds, or we'd try to delete a letter, but since the system wasn't quick to respond, we thought our touch didn't register and ended up tapping the back button multiple times and inadvertently erasing everything.
Aside from the touch screen, the GPS does have some tactile controls. On the left side, there's a back key, a mute button, and an external antenna jack; there is a 3.5mm headphone jack and external volume controls on the right side, which we always appreciate since then you don't have to dig through menus to adjust the volume. The top of the unit holds the SD expansion slot and the power button. A mini USB port and reset hole are on the bottom, but be aware that when you're using the car charger, you need to plug it into the mini USB port on the vehicle mount and not the one on the unit.
The Navigon 8100T comes packaged with a car charger, a vehicle mount, an SD card preloaded with maps and points of interest, a soft protective pouch, and reference material. Navigon's Web site states that the 8100T comes with an adhesive disc for the dashboard, but our sales package didn't include one. The company reassured us that this was just a mistake and all others will ship with the accessory. The vehicle mount itself is similar to the one that ships with the Navigon 7100. It consists of one long arm and a suction cup. It's quite modern looking and works well, but we still prefer the more traditional vehicle mounts, since they allow for more adjustments as far as placement and angles.
Aside from the 3D panorama views, the Navigon 8100T offers a feature list very similar to that of the Navigon 7200T. The GPS is equipped with a SiRFStarIII GPS chip and comes with an SD card preloaded with maps of the United States and Canada and 5 million points of interest. To plan a trip, you can enter a location by specific address, point of interest, recent destination, user-defined home, and so forth. You can also enter addresses via the voice-command system. As with the 7200T, you will have to read a short paragraph so the system can learn your voice. It's also recommended you do this exercise in the car so the GPS can get the optimal settings for the environment. Unlike the Garmin Nuvi 880, the voice command system is limited to just address entry and can't be used for other tasks.
