Since finding and using MagicEarth for maps, it is VASTLY more superior than CoMaps for use in vehicle as a satnav.
The user interface is 10x better, more intuitive, more straightforward, but most importantly MagicEarth incorporates live traffic into your journey route.
Re CoMaps : Is there any possibility of changing themes to improve user interface to match MagicEarth? or provide a hook to live traffic overlaying?
If not I may have to remove CoMaps.
