The Nav-u NV-U93T and NV-U83 both feature 4.8-inch widescreen displays that adjust their brightness automatically based on surrounding light conditions. Both can be paired with Bluetooth mobile phones so you can make and receive hands-free calls.
Another intriguing feature carried over from the current range is Gesture Command, which allows frequent destinations to be stored and then called up when drawing a specific line or shape on the screen.
The NV-U93T comes preloaded with a pan-European map for international drivers, as well as real-time traffic updates (optional on the NV-U83), while the NV-U83 contains domestic maps.
The NV-U73T and NV-U53 have smaller 4.3-inch screens (up from 3.5-inch on the equivalent current models) and aren't Bluetooth-compatible, but are otherwise identical to their larger compatriots.
The updated Nav-u range will be available in November, with prices to be confirmed.
