When I went to upload new fireware on my F500 today, it did not update per instruction, it did nothing. I know I downloaded...'cause I checked it from my computer before inserting it to my F500. Anyhow, when I manually checked the downloaded files from F500, my SD card listed my personal POI listings. How is this possible when I re-formatted the SD card before downloading new fireware; only file on the card was new fireware????? Do I have to change some setting before uploading it????? BTW, my card is set FAT32 per instruction. Thanks.
