I down loaded the Nav and system update last night to this laptop. It was S L L O O O O W W W for sure down loading even with good high speed connection. But, it transferred to my memory stick in just seconds. Tonight I did the update on the White Knight. The insturctions said to expect an hour and that the last little bit would take a long time. But, I started a 5:45, got busy with removing the seat and fitting it to a shipping box and tinkering about some, at 6:00 I noticed the radio began playing! I changed the radio to headphones so as to not have to hear static and within a few seconds the screen asking if I wanted to up YES or NO was back on and "NO" is the final step. I was prepared for the typical frustration.
