Really was good at the time it came out, but now pales in comparison to Google Maps that has traffic routing for navigation. I found this version was killing my iPhone battery (48%) of usage. I had wondered what was going on, and I had not used this app in a long time, but when I checked my battery usage this was the culprit. Anyhow, app is OK particularly if they fix battery issue, but there are better alternatives for traffic.
