Now that the '07 LS is getting XM Nav Traffic displays, does anyone know if we can upgrade our IS's with Nav to the same service?

 

I heard we cant... but if its possible, I would love that feature. I hate LA traffic.

 

I would love to have this feature...I know the commute traffic patterns pretty well but it would still be useful for biz trips or weekends hopefully somebody will figure out a retrofit kit or maybe we'll even get it as a factory option soon! I don't think the 07 IS has the feature available so it will probably be a DIY retrofit
