Up until a few years ago, personal navigation systems were considered a must-have for most drivers since they drastically reduced the chances of getting lost. But the tides have turned and demand for these gadgets is plummeting: 7.5 million personal navigation devices sold in 2012 in North America, down from a peak of 18 million in 2009, according to the latest data from Berg Insight, a Swedish research company.
直到几年前，个人导航系统还被多数驾车者视为必需品，因为它们可以大大降低迷路的几率。但当前潮流发生了逆转，对这类设备的需求在直线下降：瑞典研究公司Berg Insight的最新数据显示，2012年北美卖出了750万台个人导航设备，低于2009年1,800万台的峰值。
The need for this service still exists, but consumers can get it for a lot cheaper. Rather than paying $70 to $300 for a new GPS device, drivers can use map apps to get around. They're available on most smartphones or free to download.
对导航服务的需求仍然存在，但消费者现在能以便宜得多的价格获得此项服务。驾车者不必花费70到300美元购买新的GPS设备，他们可以使用地图应用程序来导航。多数智能手机都有这些应用，也可以免费下载。
Separately, many new cars come with built-in navigation systems: 49% of 2013 model-year vehicles have a standard navigation system (in at least one of their styles), up from 33% of 2010 models, according to Edmunds.com.
另外，许多新车配有内置导航系统：汽车资讯网站Edmunds.com 的数据显示，2013车型年的车辆有49%配有标准导航系统（至少有一款车型会配置），高于2010年的33%。
