（5）導(dǎo)航系統(tǒng)

????不管是原廠的還是在汽配城加裝的,，它們都讓我們省了很多事（除了有些時候它們也會莫名其妙地讓我們繞彎路）,。即使你知道你想去哪里，你也可以在導(dǎo)航上看看你大概到達的時間——然后可以努力在那個時間之內(nèi)到達,。

5. Navigation system

????Manufacturer-installed or aftermarket, they save lots of hassle (except for those odd times when they lead you astray). Even if you know where you're going, you can program the navi to find out what time you are expected to arrive -- and then try to beat the clock.
