Hi Guys, I am new to the thread and almost about to buy my new AVIC-Z2. I would like to do the install myself, but need some help regarding some accessories.

Vehical is a w203 Mercedes 2007 C230.

1. What is the Part Number/Manufacturer for the wirering Harness.

2. What is the Part Number/Manufacturer for the Steering Control Module.

3. Can the Head Unit be hooked up to the Speedometer, Do i need anything additional.

4. Do I need anything additional to hook up the rear camera to the gear, so when i put the car in reverse the camera is activated.

Thanks Guys, I appreciate your help.

YOU HAVE MORE PROBLEMS THAN YOU EVER KNEW!!!

Everything on that car uses a fiberoptic system. Your harness will run you a couple g's. Enjoy!

i can strongly recommend that you have it professionally installed and do a sound system along with the z2. hes right it is fiber optic and not a car to tinker with. get an experienced installer and pay them what they ask, as its worth it working on that car

Do a search on ebay for CA-R-PI.133, you will need to order it from overseas as it is not sold in the US.

It does provide all (including reverse / vss / ect) connections though; without cutting any of the factory wiring.
