The GPS receiver is located at the top (and rear) of the device and therefore when you are trying to establish a GPS connection, ensure you do not cover the antenna with your hand. The GPS connection may take several minutes depending on your location, weather and in-vehicle or open space. Do note that using the GPS receiver tends to drain the battery faster.

We tried the GPS function in the bus and on the streets and the N78 managed to pinpoint our location in approximately three minutes. (At some places, the time to get the location is longer). Because the N78 comes preinstalled with the Singapore map, you can easily see where you are. Besides the 2D and 3D map feature, you can also find place using keyword, address etc, or zoom in or out using the "*" and "#" key respectively. On top of that, you can also display your current location based on your GPS position by pressing "0".

To use GPS data, the receiver must receive the position information from at least three satellites in order to calculate the coordinates of your current location. In addition, the N78 also supports Assisted-GPS (A-GPS) which retrieves assistance data over a packet data connection to calculate the coordinates of your current location when the phone is receiving signals from the satellites. This helps to obtain the GPS position faster.
