Like Schwarzenegger in Terminator, the Satmap Active 12 is a big, clever robot that's hard to understand. Its bright, hi-res 3.5in screen and comprehensive OS mapping (in either scale) make it the only real choice for serious trips into serious hills.
Sadly there's no touchscreen, and control is often awkward via seven stiff buttons and one under-sprung joystick. The accompanying software works but has the ugly, unintuitive complexity of a download from 1998 - you learn to serve it, not the other way around.
Further mapping comes via SD card, while emergency battery caddies, tough rubberised cases and Bluetooth sensor connectivity mean it's totally prepared for big adventures. Once you've learned how to use it (you'll need the instructions), it's a winner.
