I just used it to compare the Wintec at 10Hz (see my thread in Accessories) and the internal. I had to use some unix sed scripts and one of the utils to pull the Nok out separate, but here they are - the Nok doesn't begin for a while. Note if you have the time slider enabled, you will have to select the time you want to see.

The Wintec and Nokia were to either side the center of the top of my dash and I was listening to an MP3 and for the first part doing the google maps web page.
