You have to purchase maps separately

You have to purchase maps separately, so for casual use I recommend using Track Exporter and the free Google Earth instead. These pictures show the cable and its mating pins on the back of the watch. You can also see a screw in the strap -- according to Suunto, the strap is user-replaceable; a nice touch.The caseback is smooth and contoured for a comfortable fit. The curvature of the strap and the 57mm size keep it firmly in place during strenuous activity. The buttons are, as far as I can tell, the same as those on the X9i: Rubber coated, and requiring a too-firm press to activate. The compass can work without the GPS on, yielding an intermediate power consumption mode for hiking or where the GPS can't get a signal (cities, dense forest, canyons, caves). The bearing lock is a great help in those situations. To connect the X10 to your computer, there's a spring-loaded USB cable with a jaw connector on one end and USB-A connector on the other. Once plugged in, the watch starts charging automatically and can talk to the supplied software. Note that there is no planned or extant Macintosh support, so you have to use an emulator to communicate.Here's a screenshot of the Suunto software, showing data from the bike ride above: As you can see, the GPS data is plotted on a blank canvas.I had problems determining when I had pressed one, as the display can sometimes lag a bit. I'm hoping Suunto improves these in the next model. That being said, they work and seem durable. Overall, the X10 is a nice set of improvements from the X9, and I like it. I'm not sure if I'd get the normal version or the reverse LCD X10m version pictured, but both are available online.
