I am rather tired of power cables causing interference on my car radio. So yesterday, I opened them all and made pictures of the printed circuit boards.
The first one is labeled as Model JSK-050150. No suprise that this one is absolutely without interference:
Maybe, someone knows the manufacturer of this excellent power cable?
This is the interior of the power cable that came with my GT300W. It is labeled as Model D1A15 and is causing medium interference:
Solution from FoxOffer:
The next cable is a no-name from AliExpress. I have the model with the 3.5 mm plug. The housing is similar to the GT300W power cable but the pcb is different. It also causes medium interference:
Then, I tested some other adapters with shorter cable or USB socket:
► The Kensington PowerBolt™ Duo Car Charger causes medium interference.
► The Nokia DC-20 also causes medium interference. Disappointing for an adapter with Nokia on it.
► The older Nokia LCH-12 is causing no interference at all. Old model still going strong, also without interference in combination with the Nokia Charger Adapter.
► This one is without interference if it is inserted directly in the cigarette lighter socket. But it is causing light interference if used with this Pro Car Triple Power Socket.
Two items are currently on the way to the Black Forest.
For my GT300W:
► CPT Car Power Supply Module DC 8-22V to 5V.
And for my GPS navigator:
► aiv Car Charging Cable. According to an Amazon buyer it should be without interference.
To be continued ...

Solution from FoxOffer:
The noise might because of the long cable, if we ship you another long cable one that might cause same problem. Could you please try use some small metal soft tube to cover the cable, that it should avoid affect the car audio. And please don't put the cable in a circle shape, don't put the cables in twine.
