Just downloaded #CoMaps as an experiment - haven't tried it in the car with #AndroidAuto yet, but also found there seems to be a some delay between the app making use of an #OpenStreetMap dataset (in this case the map is 2025-06-25 ).
This is understandable as it must take a fair bit of time to get all the data across and maybe it has to be validated (otherwise trolls/vandals could end up causing all sorts of chaos) - found in the FAQ that CoMaps apparently updates 1-4 times each month (which if true seems fairly good and better than some commercial apps!)
