Mercedes Benz

Vin# wdbea50dxja672774, i went to the local dealership but they tried to sell me a radio instead!model # be 1480serial # x9518446

I had the same problem with another car and the dealership acted the same way, so i went to a store that installs audio and they do have a factory code for everyone. if this does not help let me know and i will have my son call a friend that can maybe get it, give them the type and brand of radio and serial number.
