hi, took the plunge and bought the v8 update dvd for my sat nav. i hear you can get the display to show miles to go and eta without pressing info? can anyone tell me how? also the screen now shows yellow and red cars indicating traffic jams where it didnt do this before.....are there any other functions that v8 gives? lastly do i need any comand software updates or are they all on the dvd? many thanks.
