Just installed version 1.0.68 and now have the following problem: After creating a route and then hitting "Tools - Simulate route - Simulate" the app calculates the route and then hangs. I can only kill it via App Manager.
First time clear cache application help resolve the problem but after Navigator restart problem come back. In my case help me change value in "GPS position file format" option from "Save as GPX" to "Do not save" and this change help me resolve problem.
