Audi Concert Radio cassette to SD-USB
I saw a modding of the built in radio "Audi Concert" with a replacement of the internal cassette unit with a SD-USB (this was inside the radio, not an external reader.
Someone should say there are some cassette adapters with MP3 players but, due analogic-analogic connection throught the magnetic heads, the sound is not that good. More, my radio stop to load cassette, so I definitely cannot use that.
Here the link I saw.
Any hint should be appreciated.
Is this a good question?
