Bluetooth is also integrated. After the usual shenanigans associated with Bluetooth, we were able to pair the Qstarz with a Pocket PC PDA, and then use it as an external GPS with the Navman SmartST sat-nav software installed on the PDA. We didn't need to install extra drivers to get this working, but there are drivers included for use with various handheld devices, including Symbian and Windows CE.
However, it's the supplied PC software which really brings the Qstarz into its own. This comes on a 5cm CD, so won't be very useful for slot-loading optical drives. The main app is Qstarz PC Suite, which includes QSports V1, Travel Recorder V4, and a GPS driver so you can use the device with PC navigation software.
Within the main suite, QSports V1 is the primary facility for keeping track of your sporting achievements. You import logged data from the Explorer 2000, telling the software which kind of activity the log represents. Each imported data set becomes a track, which can then be displayed and analysed in a number of ways. The Summary tells you how long you took, the distance travelled, plus average and maximum speed. It also calculates the amount of calories burned based on the type of activity you specified when you imported the data. Since elevation is also tracked, you can see average speeds for ascent and descent, making it possible to keep track of how well you run or cycle up hills. The software is smart enough to exclude times when you were clearly standing still from these calculations, which is handy if you're exercising in urban areas where you have to stop for traffic lights or when crossing the road.
More visual treats are in store elsewhere in the QSports interface. The Google Map for the route you have taken is brought into the app, and your route drawn onto it. A graph shows your speed at points during your journey, and switching to the Play tab links this graph directly to the map. So you can see exactly how fast you were going at different points of the journey. Although the QSports app is not aimed at powered activities other than motor cycling, you could use the playback facility to analyse your performance around a racetrack, albeit at a fairly general level.
