Installed my New Aftermarket HU but memory not radio working
Thanks to you my family here on MBworld.I have just installed my aftermarket Pioneer radio successfully in my 98 E320. . The problem now is that the memory for the clock and radio are not working. I have to reset everything each time I restart the ignition. What did I do wrong with the wiring ? Can anyone help ?

Check the patch cable from the Pioneer to the MB wiring harness. There should be two 12 v lines. One switched by the ignition and one permanently on. That one maintains the station settings.
