I've been using it for a few days and I must say it works pretty good. If you drive in traffic daily (like I do) then its worth the $10. LA traffic can be such a killer that I look at it as money well spent. It's a beautiful thing when you see that flashing red line warning you about a traffic jam miles before you get stuck in it. This gives you the opportunity to plan and reroute your destination. It will also warn you about accidents ahead and give average speeds at various points along the route. Overall, I'm pleased with the service. I didn't go for the stocks, weather, etc. I have no use
