Needs improvements to be great – GPS Navigation (Sat Nav) Review

The app is based on OpenStreetMaps. This is great. But the offline map needs to be updated frequently to reflect the latest changes to the OSM data. Seems like the app doesn't download the most recent version of OSM data. Other shortcomings include: 1- Street Names do not support Arabic transcription. They can't be read. 2- Voice Navigation needs improvements. The voice doesn't help on lanes and which lanes to keep before reaching a turn. 3- Settings are not stable! Each time I open the app I have to reset Ml/ft to KM/m . 4- Zoom levels are too far for navigation. The zoom levels should be based on driving speeds. 5- OSM provides "max speed" data for all types of roads but the app doesn't use this data to warn drivers of over-speeding.
