Nokia Drive on the Lumia 710 has an advanced dashboard that gives ETA, etc:
With Nokia Drive, you’ll know more about the progress of your journey with the advanced dashboard. Get details like your estimated time of arrival and the time left to your destination.
While I've been this come up a couple of times while I'm driving, it's been by accident and I've not found a way to "make" the advanced dashboard display. I downloaded the manual, but it doesn't give that level of detail.
This one size fits all resource is a little confusing as Nokia Drive upon Lumia 710 is v220.127.116.1106 using map data 0.2.47.103 (same as later Symbian devices) whereas Windows Phone 8 Lumia use Nokia Drive + Beta v18.104.22.1681 using different map data set 22.214.171.124!
