也不盡然。我同時都用。

剛剛買了第二個7"GPS，雖然我有三部智能手機。其實有5部，但不能都有數據計劃。 

GPS has limited function, however it doesn't requires dataplan, and is much faster in some cases in selecting routes. Find models that has life time update and traffic info would help a lot. 

I agree cell phone has good GPS apps, but still not as easy to use as a dedicated GPS, especially large screen units.

Never can understand how to use anything smaller than 4" GPS!

所有跟帖： 

• 另外在沒有手機信號的偏僻地區和山區（美國中部山區），還是得用GPS。 -宰相肚- ♀ (0 bytes) () 06/03/2013 postreply 10:53:48
