If you have a Nokia N810 Internet Tablet, and have been fed up with the slow GPS lock times, then there is a solution. Firstly, you need to install the new OS firmware (Diablo) onto your machine using the Nokia Internet Tablet Firmware Updater (Windows only). Then, you need to install the A-GPS additional program. The A-GPS program, will help locate you whilst the GPS continues to try to lock. You give the application a very rough location in the world (by clicking on a map), and it will then use an internet connection to improve that link. However, as well as supporting a link via Bluetooth to a mobile phone (which will use the phone’s cell tower IDs to locate you), it’s also possible to locate you via WiFi. It achieves this by feeding the initial GPS data back to a central computer at Nokia which helps process those fragments of GPS information to produce a location faster than the lock.
This update makes the Diablo update well worth applying. Although things are perfect yet (most apps need the author to confirm compatibility and provide their applications to the new application repositories), you can still access the old “Chinook” software respositories (unlike the last major OS jump, everything is binary compatible this time).
Now the only thing remaining is for Nokia to have a word with Wayfinder and get them to update the actual maps. The maps included with the tablet are from 2006/7, and since then Nokia have updated the Nokia Maps (for Symbian) a couple of times, so there’s no reason why they shouldn’t sort this out. In the meantime, you may want to look at Maemo-Mapper, which uses OpenStreetMap map data, which is constantly being added to and updated, and because Maemo-Mapper uses the built in GPS support, it also benefits from the new A-GPS faster lock times.
