Maybe we should move this to a VW forum... wait, I can make it radio related... I replaced some hoses and the pickup tube in the windshield washer system, pressurized it... no joy. The switch on the dash was leaking, but I didn't figure that out 'till the ww solution dripped all over and soaked the new Kenwood stereo head unit I had just installed a week earlier! (See, there's the radio related part.) Fortunately a few blasts with compressed air, WD-40 on the connectors and overnight with a fan blowing on it cured the radio problem. Still need to get a new wiper switch. In winter storage now... a project for next summer.
In '69 I bought a used '61 VW Beetle for $284, which was all I could afford back then. It was the first car I ever owned, and was a rust bucket from one end to the other. The handle at the front (for the trunk; the engine hood was at the rear) had fallen through, so that the trunk lid had to be tied down to the bumper to keep it shut. I eventually managed to fix the handle in place by surrounding it with an epoxy body filler.
Talk about minimalist: The windshield washer used pressure from the spare tire as a pump. The windshield could not be defrosted, as there was no fan to circulate the warm air, which was from the engine block. There was also no gas gauge! A lever on the floor could be flipped to a small reserve of gas at the bottom of the tank. I was never sure whether I was running on the reserve or the main supply, until I ran out of gas one day in the middle of a mountain highway with a logging truck bearing down on me. Fortunately I was able to coast to the side of the road just in time, and managed to complete the trip on the reserve.
That was the car in which I learned how to use a manual transmission, and the gear synchronization was way off, so that I had to learn the technique of double-clutching. I got stuck in neutral one day as I was about to turn a corner, and nearly lost control of the car.
Wish I still had a picture of that old wreck!
