Most GPS models will allow you to choose your routing preferences, such as the shortest distance, the fastest time, if you want to avoid toll road. Some advanced feature will even check the current traffic information and re-route you if the existing route has traffic jam. Another good feature is to find POS or points of interests such as hotel, restaurants, gas stations and etc.
