Do I need to rewire?

Hello, I have a problem. I have two car radios here, one from Sony and one from Medion. They are pretty good, but when I turn my car off, they both reset, so I hear the bass again. The radio station is back on 85.7 for both of them. I then installed it at a friend's house and neither of them resets, but the radios get ignition plus, ground and permanent plus in my car, but there is a blue cable on the plugs that are not connected. Do they belong together so that the radio gets power and saves the data?

Switched (red) and continuous increase (yellow) are exchanged on some cars. Easy to trade and it should work

No transmitter memory without continuous plus

There’s too little tension.

You just lack the continuous increase. This is interchanged from time to time in the original cable harness with ignition plus. But you can easily measure out what is and then spin around accordingly

The continuous increase on the cable harness from the car and on the cable harness from the radio are very fond of a different pin and thus interchanged

How about the next time with phrases so that it’s not so laborious to understand what you want? If you do not have a continuous increase in your original wiring, but only have ignition voltage (which is quite funny to me), then you can still transfer a second line, where is the problem?

Blue is on the radio for the automatic antenna. Speak the voltage that the radio switches on even when switching on. You can see how the pins have to be occupied (ignition voltage/duration increase) in the manual.
