Normal car navigation system are generally not precise enough, or don't show the coordinates at all. For Geocaching, or very precise locations, you need an exactness of less than 5 meters. This can only be achieved with receiving a high number of satellites and support of WAAS/EGNOS.
Anyone knows if the G1 uses WAAS/EGNOS, and if the precision is better than 5 meters on perfect conditions?
