Hello,   I just installed a new radio on my Skoda Fabia 2005 MK1. It's a cheap thing but the old one broke.   I used the connector adaptors that it came with to attach it up to the car and i bought an antennae booster thing. My presets wouldn't save so i looked online and found that I had to use the bullet connectors to swap over the red and yellow wire. Now the presets save. And when I turn the engine off and take the key out the ignition I can't turn the radio on.
