Real time traffic info??kjh

[pseto]

I have RTTI in my coupe and its great to have. The traffic data is a little slow since its updated every few minutes. Its all based on road sensor data so if there are no road sensors, then you get no info. So far, it just works on major highways and roads, so more coverage would be nice (lets get with it DOT). However having RTTI makes nav a must have IMO as it will only get better as more traffic data becomes available. I almost always have the nav screen up everywhere I go (even if I don't have a destination input) so I can see potential delays. If you live in or drive thru a lot of large cities its a very valuable daily thing to have.
