The Nav in the '08 is that best unit I have ever encountered. This is my first experience with XM Traffic and it blows me away how good it is. It's reporting traffic so accurately I'm totally amazed. I noticed today that as I approached a highway interchange and the exits on the cloverleaf appeared all these skinny arrows just started swarming around on all the secondary roads and the exit roads. I couldn't figure out what they were doing. I looked in the manual and there was not as detailed instructuions as I would like. I wonder if a better manual is available online? Anyhow, can anyone figure out what all the skinny arrows mean? :hmm:

Direction of one-way streets?

They are showing the street directions.
