The Evesham Nav-Cam 7500's maps are stored on a 256MB SD (secure digital) card covering the UK and Ireland. For our money, it did a better job than the MyGuide SilverGuide 5000 NAV (which we'll be reviewing on Monday) of picking through the concrete jungle and delivering us to where we wanted to be. It efficiently took us to Sheffield and found a Nottingham suburb without too much difficulty, although it wasn't much use when we wanted to find more remote locations.
Design-wise, the Evesham is a beast of a unit, but while the buttons are generously proportioned, we found some controls, such as the power switch, fiddly and ineffective. Keeping the device charged was another irritant – four hours of charging will earn you just two hours of use.
Anyone who's used satnav products before will be aware that the maps and interface are at least as important as the unit itself. When we tested a range of GPS products for our round-up in the September issue, we particularly prized easy access to volume control – invaluable for avoiding road rage caused by continual nagging in a traffic jam.
Luckily, both MyGuide and Evesham have chosen to include a TMC (Traffic Message Channel) function, so you may be able to avoid the jams entirely. This provides real-time alerts when the road ahead is logjammed, then quickly serves up alternative routes.
