Does your radio go off during engine start?

[lmn]

Ok I made a similar circuit for the constant yellow +12V cable but I placed just 1 Diode Schottky followed by the cap (6x 2.7v 5Farad in serial) and now it work like a charm!
The radio does not switch Off/On anymore when I ignition the engine.
And yes when I remove the key it switch off normaly.

Thank you very much!

I have never noticed that before in any car' I will have to test them all!
