lame flash memory - updates take forever

If the flash memory of the Vision 700 just lame is like the F12, which I have for over a year, then you should leave it alone. I just made the third update of the F12, it has again lasted ten hours. Why an expensive device you can install a lame memory in such a way in which the transfer of 200 MB whopping takes two hours, is beyond me. Then you get even the sly tip to transfer the new maps directly onto an SD card and then put it in the Navi, because that would go faster. So it does not retain customers. If I do not get a free map update more, I navigate faster and more convenient with my Galaxy S2 smartphone.
