I recently bought the Tablet because I was told that the Tablet can double up as a GPS. I was skeptical on how it can retain the navigation if the wi-fi is lost after my car leaves the home wi-fi range. One of my friends told me that the Tablet can use the satellite directly like the GPS if we download an app. I am unable to reach out to my friend after I bought the tablet. Is there an app that would help double as a GPS and how do I get it? Any help greatly appreciated.
