Elegant and sleek looking, TomTom's GO 930 is one the best looking GPS units I've tested. The black rubberized plastic feels well built, and doesn't pickup fingerprints easily. The included windshield mount is easy to use, and holds the GPS securely in place when driving. The windshield mount isn't powered, so you'll need to connect the power cable to the GO 930 when docking or undocking the GPS from the windshield mount.

There's much to like about TomTom's GO 930, but perhaps the most significant features are Map Share and Map Corrections. Unlike traditional GPS devices where it can take years to correct mapping errors, the GO 930 lets drivers correct mapping errors directly on the device, and then share those corrections with other TomTom drivers via TomTom's Map Share program. TomTom estimates that a typical 1 hour trip will be influenced by more than 20 corrections. The GO 930 can automatically download mapping corrections each time it is docked to a computer running TomTom's HOME software (included). Map Share is free, and represents a significant and continuous improvement to the quality of TomTom's maps.

Also new to the TomTom GO 930 is IQ Routes, an innovative feature that incorporate historical traffic patterns into route calculations, allowing the GPS to make different routing decisions based on the time of day, and day of the week.

The GO 930 is one of the few GPS units in its price class to come with maps of both North America and Europe. International buyers will also appreciate the device's extensive list of supported languages.

I was also impressed with the GO 930's strong internal FM transmitter, loads of customization options, and Enhanced Positioning Technology (EPT) that lets the device continue tracking your position even during brief GPS signal outages, such as when driving through a tunnel.

However, it's not all good news for the GO 930. The speech recognition features of the GO 930 feel clumsily and incomplete. Accuracy is inconsistent, and it isn't possible to operate the device using voice commands alone. Only a limited number of voice commands are supported, and you'll still need to touch the screen to begin navigating. Most of the time it's just easier and faster to use the touch-screen controls rather than voice commands.

Advanced Lane Guidance, a feature that displays 3D renderings of upcoming turns, is only available in very few areas, seriously limiting the value of an otherwise handy map enhancement. The GO 930's screen isn't as bright as it should be, and TomTom's HOME software is so buggy I had to uninstall it in order to restore my PC to a functioning state. Bluetooth support is poor, and TomTom's routing engine isn't as good as Garmin's or Magellan's.

Also disappointing is the GO 930's reliance on Bluetooth for TomTom's Services; you'll need to pair a compatible Bluetooth enabled cell phone with the GO 930 in order to make use of services like Traffic, Weather, & Fuel Prices.

TomTom's map screen can appear cluttered to some drivers, though it is possible to customize the map screen to suit your own personal taste.

The TomTom GO 930 delivers several exciting and innovative features that improve the value proposition of GPS navigation. Packed with new features and advanced technology, the GO 930 isn't as easy to use as some other GPS devices, and can be challenging for less tech-savy consumers. Still, the GO 930's North American and European maps, and long list of features make this a unique GPS that's competitively priced.
