Hello friends, I have installed a new ignition switch on my MAN 8.153http://www.lkw-teile24.de/…/…lter-MAN-L2000-F2000-M2000::4305.html Now the radio only goes when the engine is switched off when I turn on the radio and then start the engine it goes off What did I do wrong – maybe under the dashboard came to a cable or can you plug the 7pin plug upside down – can now not remember greeting Rolf
