The factory CD head unit I had in my car until about this time last year, a mid-90’s single DIN Ford "premium unit actually made for ford by Sony, was not supposed to play CD-Rs but it would play SOME CD-R discs
The discs tried? Azo (Bright Deep Blue) or Cyanine (Blue-Green), but not the pale (greenish silver) Pthalocyanine CD-R discs.
The aftermarket unit I have now will play almost any CD-R, but is sometimes sensitive about how the disc lead in is done.
It will choke on CD-Text discs unless I program a short pregap on track 1 into the cue sheet before burning the disc.
my disc changer will “eat” anyting I feed it CD-R, CDRW, etc…
Most name brand aftermarketCD head units made 2004-ish or later will play RW discs, I have yet to see a factory unit that will play the RW’s reliably.
Though I should note that the “slow” (1x, 2x or 4x) RW discs are hopeless.
The “High speed” (10X) and “Ultra Speed” RW’s work better because even to the naked eye it’s easy to distinguish the written part from the unwitten part.
Expirement, a different brand or “faster” RW discs may work for you.
Personally I like RW’s because of the obvious economical benefits
And though the data degrades over time, it’s easy enough to erase and rewrite them periodically.
