Just a short info here for anyone who might be interested. Maybe all of you know this but it was news to me but then again I am technically challenged! After purchasing my samsung tab 3 and downloading the avare navigation application I discovered that you do not need a wifi connection to operate the application. Evidently the GPS chipset works as its own and therefore you will not use up any data well using this application. So far I really like this particular app although I'm sure there are other really good ones out there. Doran N186RC
