I recently bought a Safari and I just used it for the first time today. Looking at the maps it had several streets around my area and the street my house is on. I then saw there was the 1.5.1 update so I applied it. I am not sure what the original firmware was because I did not check before applying, but the theme was yellow before update and gray now. The main problem I have with the update is it seems to have lost detail on the streets. Now it only has major streets around my town. I did not delete anything on the SD card or format, and there were only waypoints on there to begin with. Also, I tried all 3 different detail settings and every other setting I can think of. I tried downgrading to 1.4 and 1.1 to see if I could get all the streets back, but it would say "update complete" immediately after starting and it did not actually apply the older version because I can see in the about page that it is 1.5xxx still.
I need help because I don't understand why the maps lost detail with an update.
Thanks
