The Lowrance Gen-2 is not wifi. To get wifi and being able to view it and control it with a tablet you need a Gen-3 or the excellent Elite Ti that comes in 5-7-9 and soon in 12''.
Touch screen, wifi, bluetooth, 2D, Chirp, downscan and structure scan with the Totalscan transducer. Can't be beat for the price & quality.
With the latest update you can also create you're own map live on the screen if you are running a Navionics card with a recent subscription.
