I just purchased a 140S from a local Best Buy. I immediately noticed an improvement in routing. The 140S took me home from the store via the same route I would have chosen. The 130S always took me home via a somewhat inferior route.\n\nI like the advanced lane guidance (in the lower left hand corner of the screen). I have not yet seen a static image for any intersections in my area (Rochester, NY).\n\nThere are some minor changes to the menus. There is 64 mb of ram as compared to 32 mb in the 130S and 2 GB of memory as compared to 1 GB of memory in the 130S. The computer voices are different. \n\nI am very pleased. I think the addition of IQ Routes make it well worth the upgrade.
