Got my Craig back in the car today. I asked Elvis to replace the tuning chip and fix my long-dead display, he did an amazing job! The display is perfect, good as new. And I can finally tune in my favourite stations.
I also made a little bracket that prevents the tape door from being pushed in, so the new wiring won't be damaged. I'm not going to use the tape anyway!
The hard part was getting the radio back in the car - I put it in through the hole for the vents. The little screw at the back of the radio is a pain to put in, so I changed it for a slightly longer one sticking outwards from inside the unit, and put a nut on it to secure it in the dash.
And the rubber connecting sleeves for the air vents... what a nightmare. Someone mentioned using thin strips of plastic to slide the vents into the sleeves, so I tried it, and it worked a charm.
And with that, my car's interior is complete!
