Israel - iGO primo Nextgen

Just back from a month in Israel. After having so much trouble with the local maps and street sign as well as unknowingly racking up data charges using the preloaded map on my iPhone 4 I decided to load this app. Never once did I have a problem. I primarily stayed in Haifa where the streets are confusing enough without the road construction going on. Several times I had to turn off of the predetermined to route because of construction and this app immediately recalculated and put me back on course. So many features are in this app and you really have to play with it to get the most out of it. I did use this app to travel to all points of Israel and never once did it let me down. No data roaming charges at all. Definitely love the POI feature as well. This came in handy to find hotels, food etc. when I really had no idea where I was at. I will definitely get this app for any other countries I will travel in. Update 12-June-17: Was 5 stars but now downgraded to 1 star. I have downloaded the app again on an iPhone 7. Now I can't get it to display in English. There is one button (I assume I am in the setup mode but since it is in Hebrew, I don't know what it means) and every time I have tapped it the screen goes black. I have deleted and reloaded three times now with no success. I even attempted to press random buttons hoping to get lucky. I have no choice but to dump the app as it is now useless. Oddly the Italy and Costa Rica maps still function correctly.
