as today my WiFi got some problems, so I has to pause several times of updating map. As I complete around 70% approx(15+33+12+12) in four times. But it start from scratch again & again. May ne I will try for 100% combine then wait & watch.I believe from where it left off but I could be wrong.
sorry to say yup you are wrong as map has to download continuous as by some portion done I downloaded maps updates around 1.2GB whereas updates was 266MB.I believe from where it left off but I could be wrong.
