Will Google Navigation work without WiFi on Android tablet I have a Toshiba Excite tablet with android ice cream that has WiFi only (no cellular) that has Google Navigation (Beta) app on it and also Google map (Beta) app. I want to use the tablet in London England and Paris France. Will it work while walking around the city if I can't stay connected to WiFi?

If you think it won't work, what app can I use offline that will?
It most likely will work, depending on a few facts:


your device must have GPS built-in
you must have the map data downloaded while connected to WiFi (e.g. using Maps (-) Offline Navigation, which fills Google Map's cache)
for navigation, you must have calculated the route in advance


I'm not sure whether Google Maps supports pre-calculation for navigation -- but even if, there's another restriction: once you hit a "closed road" (road works or the like), you're lost -- it cannot do a re-calculation of the route without network.

Also, getting a fix on GPS might be a lot slower (unless you aquire your fix while still connected to WiFi). Background is: To get a fix, GPS needs to know where which satellites are. These data are contained in what's called the Almanac. While AGPS downloads those data from the network (e.g. via mobile data), "plain GPS" does not have this feature, and thus needs to get the data directly from the satellites -- which obviously is not as fast.

If it does not work with Google Maps, there are several alternatives to be found on the Google Playstore. I successfully used Locus Map Free this way, so I know it does work. Locus lets you download map data directly from within the app, from different sources, and also offers pre-calculation of routes. This app is just one example, there are a lot more available.
