Arrived by speedy gonzalas mail today thanks.
I fully accept my roofmount requirement is somewhat unique: the analogue video output isn't long enough to reach down to my dash from the roof so while I think up an extension possibility to thread it down the A pillar and behind the dash I tried to find the wifi for a tablet - but I can't find wifi in the menu, any help there please? I'm not worried about lag as its only needed to spot quarry, not shoot it.
Also a small edit might be useful, two batteries weren't included.
