For the first few years of its existence, the personal navigation device has primarily used a 3.5in non-widescreen for budget models, a 4.3 widescreen for most premium models, and larger displays only very rarely. But recently 5in models have started to appear even at the budget end of the market, such as Mio's Spirit 685. Before the competition can catch up, Mio's other sat-nav brand, Navman, is increasing the pressure still further with the Panoramic. If five inches aren't big enough for you, the Panoramic packs a massive seven inches diagonal.
A sat-nav this big requires a specially robust mount, and Navman supplies an articulated arm with a particularly powerful suction cup. The sat-nav slips on securely, and there's a notch built in for the mini USB plug which supplies power. This means you can slide the sat-nav in and out with a single motion, although it's actually quite hard to slide out. The arm itself isn't completely solid, jiggling a little in transit, but the cup attaches so securely we wouldn't be worried about the sat-nav falling from your screen on a bumpy road.
Once you get past the supersized nature of the Panoramic, however, it's a pretty run-of-the-mill device. It's not the first 7in sat-nav we've seen, either. Mio's Navman Spirit V735 TV has the same screen size, but it has the excuse of incorporating a television receiver, so the large display is somewhat imperative. But the Panoramic's main use for the the extra visual real estate is simply map visibility.
The menu is Navman's now standard Spirit interface. This offers pages of large colourful icons, which you can scroll through with sizeable arrows. All the main functions are within easy reach, including key points of interest (POI) categories such as parking and petrol. Click one of these, and you get the nearest amenities in that category, listed by distance.
