unless MB has changed their policy...you have to visit an MB dealer with proof that you own the car and your driver's license...and of course the radio or s/n to the radio. It's much like asking for a spare key.
They usually make you fill out a simple form with all the info before they release codes or keys. However, if you can find a car radio shop with experience with MB radios, they might be able to help you.
This is a free service at MB...at least it was a few years ago when I needed their services. In any event, you're probably not that happy with the limitations of these factory radios. Everyone I know has replaced these expensive dinosaurs with digital upgrades which offer better sound quality, and all the modern features that are becoming a neccessity these days. There's nothing like a new digital tuner with a couple of hundred watt amps and some poly 3 way speakers...I love my JBL's.
I suggest you check out a local radio store and check some of these units out if you can...you'll be hooked. Remember, if you do decide to up-grade, hold on to the factory radio...keep it with the car. Its good for the re-sale.
Good luck.
If you're talking about a Mercedes Benz, I don't think you can reset the radio and nav system.

There currently is no code to get 500 Rox.
There are 2000 pounds in one ton. Therefore, 500 pounds is equal to 500/2000 = 0.25 tons.

25% of 2000= 25% * 2000= 0.25 * 2000= 500
