Hey I have a question for you guys who seem to know more about SD cards.....
If you could copy the Navteq Geo-Data on the OEM SD card and transfer that data to a higher speed SD card would you see a difference in the speed of SYNC Navigation loading and functionality?
Or is the speed determined by the hardware and Microsoft Mobile OS?
I doubt a noticeable difference would be seen, if any it would be during the initial loading after start of the car, and during lookups of POI/Destinations. Likely not enough to notice though, if you try it let us know how it goes.
