Harness for aftermarkey head unit?

I'm looking to replace the stock head unit with an aftermarket one. I was told I need a mercedes harness to make the aftermarket head unit to work. I don't know which harness I need or where to even get it. Does anybody know where to get the harness? I have an 02 c230 coupe

Are there any Car Audio shops around your area? BestBuy? They should have your harness.

Yea i went to one of the guys and he said that mercedes didnt make a harness for any c class models 02 and down. Which i think is probably not true or he might have been referring to a whole ipod integration kit

In any case what would i tell the best buy people? Like any specific name for the harness? or would i just say i need a harness that connects into an aftermarket hu

Mercedes doesn't make the wiring harness.

Just go tell them you are going to put an aftermarket stereo and you need a harness for a 2002 C230 Coupe.

It will look something like this.

Here is an ebay seller that sells the harness.

You can try sending him a question and making sure this is the right one for your car.

I went to college with "Mr. Crutchfield's" daughter. Awesome guy, and their customer service is outstanding. Please buy from them if you are satisfied with the customer service. Tons of people will use their advice, then go buy somewhere else to save a buck or two.

You need "Metra 70-9401". Its made for VW but comes with the exact connections made to fit our 02 coupes. Google it and it will look like what Karo posted.

What are you installing? A Double Din, Indash, or Single Din?

well it is not the camera, it is the cable that I need to run from the license plates to the headunit for the signals to be trasmitted to the nav screen. Laying this cable would be a real PITA....... so I was asking folks up here is there a specific route that I need to lay it so it would be relatively easier.........power for the camera, I will be drawing it from the reverse lights so it kicks in when I am reversing the car.........will see what happens....will definately have to take the rear seats out; I don't see how I can get around it to get into the trunk........I can fish it too but what route I need to take to be able to fish it so it is easier.........
