Deleted instantly another magically over rated app!

Wasted almost 2 gig of data downloading this sat nav & also UK version which I stupidly relied upon both navigating me 1000 miles of driving by car to the south of France. The app says no internet connection necessary to navigate. I must have spent a full day trying to get this application to even work. It would not navigate! I typed in my destination & clicked navigate" it did nothing! I used my wireless connection hoping that would help & played around with the app trying to get it to start while my partner was driving. What should have taken 9 hours of traveling turned into 2 days while we got lost, took the wrong turnings, junctions, & paid out over 100€ in toll roads! Do not rely on this app getting you to your destination...I wish I hadn't! Wasted 2 days of my 7 day holiday & so wished I'd purchased a proper navigation system! Why is this app highly rated when it's crap!? roads because this damn app was rubbish! Don'
