A bit pricey of a route but I got the WeatherTech shades package for the 4R, have been very happy with them. Use the windshield and rear hatch shade all the time. Occasionally use the front driver/pass ones also. Works well.
For the dash mat I went with Escape Gear (since I wanted their seat covers also)
very good investment IMO. Seems to help keep car cooler, dash is protected and audio sounds slightly better. And the perfect place to hide the horrendous Massachusetts EZ Pass unit.
