Is there much difference in updating from 8.1 to 11.1? Any system or firmware updated that makes it worth it? Or is this strictly a map and POI update?

Thanks.

i notice big change in my map, my map never show the lane in the freeway but it does now, but is mostly just the map and the POI

just upgraded from 7.1....a new ramp to highway at my work place, which put in about a year ago STILL NOT AVAILABLE IN 11.1

^ LOL. I changed from 6.1 to 10.1. All my highway ramps are updated.
