Not sure if you meant to put this in the TCH sub-forum but this was posted in the Saturn forum.

I don't know about changing the face plates out but that is something I would love to do. The blue around the radio/nav is the one thing I don't like about the TCH. I think Toyota could have taken some lessons from Honda when designing the front dash cluster (color wise).

As far as gas mileage you should see an improvement. Do a search in the TCH forum. There are many great tips on how to improve your mileage...

Welcome aboard.
