...What you want is something like Meguiers Back to Black.

Any product made for dash boards and trim that has UV protection is fine. I use Black Magic, some hate it because it tends to collect dust over time and is greasy, but if you touch up your VX daily, or several times a day like I do all you'll notice is a deep rich shine You'll get many opinions on this topic, and there is plenty of coverage in the SEARCH feature. Enjoy your VX
