Just bot a 2002 C320 with no cd changer. Bot the CD changer refurbished thinking it was an easy install. WRONG! I'm stumped! How do I get to the prewired cables? I can't figure out how to get radio out and wasn't able to fish for them from glove box! Assistance needed.

 

The are orange in color and shoudl be tucked up belhind the battery on the lining of the truck near the fusebox, At least that's where mine were on my 99 C280, I guess it might be also where the CD player is mounted on the car. But if you see a orange covered, it is not really a "wire" it is a fiber optic cable.
