and cd and 8-track players. A circa 1961 record player for the auto.

Had one in my 66 chevelle SS396

Always heard about dads 57 hudson hornet with a record player in it. Never really seen one though. The power of music eh? Can't leave home without it.

I've never heard of a mobile record player.
Did it work well? Or did it skip over every bump?

I guess the question is.... bump or BUMP? On small ones it was usually ok, maybe a skip now & then BUT on the big bumps or pot holes (the road kind-not the smoking kind), if you did not pull the record out, it was a goner. Remember cruzin listening to records by the temptation, four tops, and many other R&B greats, along with the stones, hendricks......on & on. Great times. As they said in on Golden Pond, cruz chicks and suck face.

BTW, I think in my pile of crap in my garage, I might have one that my friend gave me from his 1968 Camaro SS.
