I'm not sure if this is much help, but I have a Navagon unit for my truck. Maps are updated every quarter, or 5 months at the latest. Unlike other vehicle units, detailed traffic updates are free (it tells me about accidents, slow traffic, or cars on fire ahead of me). I would hope these same characteristics are in the mobile version, but I can't say for sure.

Again, I know it doesn't specifically answer the question.
