Microsoft released their business mapping/navigation software, MapPoint 2006, just a short time ago.  The GPS units Microsoft bundles with their products are simply rebadged Pharos devices, and previously have been iGPS-360 models.  The iGPS-360 while decent, contains the older SiRFstar IIe/LP chipset and is slower in signal acquisition and can track less satellites than the new iGPS-500’s which are SiRFstar III equipped. 

Prior to its release there had been speculation that the new iGPS-500, included in the MapPoint 2006 with GPS Locator edition, would be much smaller than the iGPS-360 units.  This would have made accessories, like the iGPS-BT Bluetooth cradle, absolutely useless with the new devices.  We’re happy to report that the new model GPS units are indeed the same size, and although they have slightly different pinouts (as shown below), all existing accessories function just fine.
