Haven't installed it yet but hope it works. Keeping WiFi on is a not well thought out option to use maps. I can't begin to list how many networks that I've used that require web authentication in order to use their WiFi network. I can't begin to say how frustrating it is when I'm driving, your phone picks up one of these saved networks, tries to connect and gets no internet connection. Looking forward to trying it out
Now if only it is possible to turn off the "feature" that disconnects you from a WiFi network (e.g. WiFi at Starbucks, Xfinity hotspots, wholefoods, Lowe's, Ikea, home depot), telling you that it might not be stable before you even have a chance to try and authenticate through a webpage
Keep up the good work!
