Fitted an xtrons head unit all is fine, downloaded waze for maps, it has Google maps built in, the trouble is neither of them are working to their full potential, ie telling me to turn left when there isn't a left etc. I'm running it off my phone tethering hotspot, it is bugging me as i got the unit specifically for the maps, i know i could run it off my phone via a USB lead but i don't really want wires in the cabin had that before when the phone and sat nav were being stuck to the screen, i have to relocate the gps antenna to see if that helps, but if its the same i might just pull it out, any suggestions would be of great help.
