1956 Chrysler Highway Hi-Fi: Detroit’s First In-Car Record Player (2017)
Here’s the story of one of the first efforts: Chrysler’s Highway Hi-Fi record player of 1956. While the player was offered across the Chrysler model lines from 1956 through 1959, it never caught on—due mainly to poor reliability, high warranty costs, and the limited variety and distribution of the Highway Hi-Fi record catalog. Despite the first misfire, Chrysler revisited the auto record player concept again in 1960-1961 with a completely different unit produced by RCA and known as the AP-1 (below).
