What is a GPS doing on a computer blog? Well, this particular GPS is a converged device. Not converged with an MP3 player (although it can play MP3s), but converged with a Windows Mobile handheld computer.

It is is the HP Compaq iPAQ rx5915 PDA, otherwise known as the HP iPaq rx5915 Travel Companion. The design is more like that of a GPS, although it is a fully functional Pocket PC with Wi-Fi (b and g), Bluetooth, standard Windows Mobile applications and it runs Windows Mobile 5.0. The main difference it that is has 2GB of onboard flash ROM, in which the maps are stored. The device comes preloaded with the maps for North America (US and Canada) including Alaska and Hawaii as well as Tom Tom navigation software, so after the first charge it is ready to go. The screen also has transflective antiglare coating designed to reduce glare and improve readability outside.

Prior to an upcoming trip I decided to update the map files, since I haven’t updated them since getting the iPaq rx5915 almost two years ago.

The installation instructions with the map update were not very positive – to get it to work you either had to delete the “iPAQ GPS” folder from Rom, which meant all your maps and the mapping software would be gone if the update wasn’t successful, or “Run the update four times. The fourth time the update is run, it will proceed successfully…. This map update requires at least 45 minutes to complete“.

I tried the map update once, and got an error message about an invalid system configuration. After re-reading the install instructions figured I would rather take a chance on map data which was a bit out of date.
