Just done an overnight trip from Newport to Wimborne and back with with 2 phones running both the nds version and ttgo and there is a difference in the routing algorithm between the 2 softwares. My htc was running the nds while my galaxy s8 was running the latest patched by dfox.
To my mind the nds version gave me the more logical route while ttgo seemed to want to take me down a country lane, unsure how this will work out long term though.
