手机gps还是最方便的，再也不用记得带gps了。相机一个道理，最后还是手机拍照最方

parks?
Then I would not prefer it, unless I have budget for two GPS devices.

发帖数: 27354 | 5 If iphone GPS only relies on phone company signal, probably yes; But iphone
should have a high-quality satellite receiver and sensor.
If a high-quality receiver is heavy, probably iphone does not have it and
will not have it in the future.

Well, it is not about GPS positioning. The point here is that iphone uses
real-time map downloaded from Apple server, which relies on your wireless
carrier's signal.

4G的卡足够了
智能手机和GPS各有各的好处

发帖数: 879 | 10 前挡左下角放个安卓手机，中间观后镜旁边吸个garmin。一般用garmin，大屏方便，声
音也大。陌生地方用google maps确认一下地点。garmin地图更新慢，有些位置有误，
有些地方找不到。
所在的新小区的路和老婆公司的新路，google maps更新了部分，garmin地图上一点也
没更新。
不知中间观后镜旁边放gps会不会违法？只是轻微的阻挡视线和观后镜视线。 |

发帖数: 17565 | 12 你没搞清楚gps信号和手机信号的关系。
gps信号在任何地方都有，但是手机信号野外就没了。
iphone自带的gps地图信息是通过手机上网随时下载的，没有手机信号就没法上网了，
哪怕有gps信号也没法导航。

发帖数: 27354 | 13 I don't think we differ on this. iphone cannot receive satellite GPS signal
since iphone has not installed a phone-signal-independent receiver.

发帖数: 10109 | 14 I think iphone (and pretty much all smartphones) has GPS receiver, you just
need to download the map information. On Nokia Lumia 920, you can download
the map/route info on the phone and use off-line navigation.

发帖数: 17565 | 16 。。。。iphone当然有内置的gps天线了，从08年的3G就有了。这么说吧，iphone买了
内置地图的软件，脱离开对网路的依赖后，可以在全球任何地方使用，拔了sim卡也没
关系。有手机信号时iphone会利用手机塔信息帮忙搜星，提高搜星速度而已，不代表没
有手机信号时iphone不能定位。
这年头连个数码相机都有GPS，你认为全球最热门的手机能没有么。

Somebody else above did say that he/she has both iphone and a stand-alone
GPS device. Perhaps (s)he is talking about an old version of iphone.

发帖数: 17565 | 19 没有的事。iphone gps性能不会低于独立GPS。实际上99%的时候iphone定位比独立GPS
快得多，因为可以利用手机信号快速搜星，一般都在三秒之内。
