Thanks, Lee. It's just that some tablet specs say...GPS: Yes...3G: NO. I thought one can't work without the other. I get confused - LOL! I have 'Navigation' on my Samsung mobile, but that can work with the WiFi and 3G when turned 'off'. Does that then rely/go on the mobile network transmitter? Anyway, thanks for your quick response.
I think that almost all of the tablets at this price range don't include GPS. I think with Google Maps you can 'cache' certain maps for when you are offline, but the Navi function requires GPS to be enabled. TBH, I think most Navi systems require GPS, I'm not sure that 3G gives enough info to Navi's to determine the exact spot you are in. 3G would certainly allow you to view maps on the move without caching them before hand.
