These types car tips and auto sound systems were definitely not the norm as they are in today’s cars. I was commuting 3 hours (round trip) each day at the time and some of the time was spent among the corn fields where there were no towers broadcasting radio signals anywhere nearby. I’m sure you can see why I felt I needed a CD player. At any rate, my wonderful dear old dad installed my brand new car (well mini van) stereo for me and all seemed to be going well until we realized that the horn no longer worked and that in order to actually use the stereo, the headlights must be on (this was also before daytime running lights were the norm as well). I’m sure you now see why I am such a huge advocate for having a professional install the car auto system. It wasn’t that my father didn’t know what he was doing, it was just that simply reading the instructions wasn’t enough to ensure that best result of the installation.
