Along with HTC P3300 we also carried a MDA Compact (HTC Magician) with an external GPS receiver and an older navigation chip SiRF Star II in order to be able to compare both devices simultaneously. During our weekend trip it helped us find three geocache treasures. Once HTC has found the satellites, it starts to navigate seamlessly. HTC P3300 helped me catch several hidden treasures Yet, let’s not forget that we are working with a sample unit, not with an officially sold model. It feels as if in HTC P3300 the navigational chip and the corresponding application were not linked. For example, iPaq hw6515 featuring a similar additional application starts to navigate within a few seconds after having been activated. Although we downloaded the most recent positional details by mobile data transfers, it took quite a long time to the communicator to locate the satellites (the sky was clear). Let’s now put an end to theoretical explanations and start practicing. At the same time it is all the same whether the necessary information is gathered via mobile data transfers, via a Wi-Fi network, or through synchronization.Ī simple application for downloading of indispensable navigation data from Internet As the satellites move constantly, however, the validity of downloaded data expires within approximately three days and a new download is required.

The above mentioned additional application helps to download all necessary information (a few KB) via Internet, advancing the start of the navigation.

The fewer the satellites the GPS receiver detects, the longer it takes it to start running. Once activated and before it determines user’s position, the receiver needs first to connect to the satellites and download detailed information about their location.

The manufacturer has used the chip SiRF Star III (the best solution in terms of price), adding a useful application for faster satellite search. This is the first “Compact' equipped with a GPS receiver. Apparently, HTC has done its best to catch up with the latest technological trends, especially the one focused on navigation.
