I have a Pinoeer DEH-P7400MP MP3 Deck for sale. It was installed in my 1996 C220 before I sold it. I purchased a wiring harness adapter for it, wich has been installed by me. I was very carefull to hook it up right. The stereo works perfectly, and will not require any cutting of the stock wiring harness to hook up.
These usually go for $100 on ebay, but since it IS used, I am looking for about $70. I can ship it out to you anywhere in the continential U.S. for cheap.
Please email me at:
maxschrepfer@comcast.net or call me at 217-493-6243 because I do not check this forum every day, due to sale of my vehicle.
