CD Player Error

I have a '98 Rivi, and i just got it yesterday. I put a cd in, and after 30 seconds or so, it pops right back out with an error code. I had the same problem in my 2000 Catera, all i had to do was reset it by holding in the power button for like 30 seconds. But this didn't work with the rivi. anyone know what i can do?

Also, it has gold tips on the exhaust, and i want to get those replaced with silver, as well as the trim around the license plate anyone know where i can find these things? i'm not big on gold. My rivi has a cloth roof, which I'm most likley going to get removed, so how much will that cost?

for the cd clean it
