The ONE has received a facelift and although the improvements are largely focused around the aesthetics, this is still one of the best value for money GPS units on the market.

As a basic, entry-level GPS unit at this price, the F20 does quite a fine job. It doesn't include speed or red light camera warnings and is thin on included accessories, but an easy to grasp interface and solid maps provide a pleasing navigational experience - even for first time GPS users.

The GPSMAP 76Cx remedies the flaws of the GPSMAP 76, adding USB connectivity and a microSD card slot.

The S50 adds Bluetooth handsfree and NavPix for a reasonable price. Although there is no camera to take NavPix photos, it's still a useful application.

The nuvi 250W is a solid unit and the widescreen display is certainly a nice touch for an entry-level model, but its missing a few features to warrant its price tag.

Although the S150 doesn't have all of the features of its more expensive sibling, Bluetooth hands-free remains, as does the excellent navigational experience.

If you are on a tight budget and don't require many advanced navigational options then the iCN 330 is for you.

Although the GPSmap 60 is functional on at least a basic level, it has a black-and-white display and a relatively high price point. With no expandable memory, slow acquisition times and a confusing control scheme, there’s no reason not to spend a little more and buy the Colorado 300.

The S102 comes at a good price, but although the navigational experience was solid, it just doesn't do enough to command a glowing rapport. There are plenty of better options available on the market.

The AVIC-S2 is well equipped and despite a somewhat confusing map experience, it remains a recommended, if not outstanding purchase.

TomTom’s latest addition to the navigation market continues the company’s fine form when it comes to the user experience. The GO 730 adds some excellent software features to a package that we’ve come to know and love.
