You will need a regulated power supply for the module (5v or 3.3v). You will need an antenna designed for a GPS.
Your module, like most GPS modules out there, outputs NMEA 0183 which is simply serial data that can be read by any microcontroller such as a PIC. It can also be plugged straight into a PC and read by common software. This will give you latitude and longitude. Your controller can calculate speed from the change in lat/long over time. Accuracy is inconsistent, often in the low 10's of feet, sometimes 50, 100, even 300 ft.
How that becomes a navigation system is up to you. You may need a vehicle speed sensor, a magnetic compass, inertial sensors (accelerometers), and rotational sensors (gyros). Software for decent vehicle road navigation is quite complicated. It needs to place you on a road even though the GPS position error may place you inside a nearby building. At times the error is large enough to place you on the wrong road although common sense would show if the position has shown you 30 ft east of your real location on the actual highway for the past 10 miles and a new road suddenly shows up 30 ft east of the highway, you aren't actually on the new road even though that's where the position data said you were.
