The ver 10 also tells you to hold right everytime there is an exit to the frontage roads in Bangkok !
It is very anoying to listen to, so i reinstalled Ver 9, that works good, i had gone from Phuket to Khon Khaen several times and some other trips as well, only a few bugs, as it want you to drive over Ranong instead of Surat Thani etc. !
So stay on 9 untill they make it better.
