Finally it works!
After months of updates from Scout, Apple & Lexus Enform I finally have a working GPS with maps. Updated to the new iOS 11.3 last night and Scout (cabled) did not crash on my way to work. Bad reviews were warranted in the past. When you have 3 vendors trying to get an app to work there are going to be problems. Hopefully it will remain stable and Scout can focus on improving the app.
