The S90i is Navman's cream of the crop, and it is certainly a fine unit. The 2-megapixel camera adds flexibility for using NavPix.

The C720t is very similar to the successful C520, so it remains a great unit with plenty of features. Unfortunately, the geotagging feature is poorly implemented, so we're not convinced this is worth the extra cost over its little brother, though the included TMC cradle kit is ideal if you are planning to use the traffic feature.

It may have a hefty price tag but the Triton 2000 offers plenty of features. The touch screen makes this device much easier to use than units that only have a navigational pad.

If you currently own a GO 720, then there is no real reason to upgrade, as most of the improvements are software upgrades. If you are looking for a high-end GPS with all of the latest features though, the GO 930 is excellent, if a little overpriced.
