Sony’s NV-U94T is the premium model of the three GPS portable automotive navigators reviewed with unique features such as a audio/video player and stereo Bluetooth technology. Both the NV-U94T and NV-U84 have large 4.8 inch touchscreen displays while the NV-74T has a smaller 4.3 inch touchscreen (the largest screen size in some other GPS brands). The screen is easier to read in bright lighting conditions due to an anti-glare coating. All models come with a Sony’s Gesture Command capability which provides quick shortcuts by tracing shapes on the touchscreen display. Spoken navigation directions benefit from the text-to-speech capability.
