Make sure there is no label on the disc and try another brand.
Hmm this is the first time that a player won't read cd-r's.
I have heard this claim over and over again and even the old SONY DVD players which are very problematic when it comes to playing Cd-r's can play some cd-r's if the disc is good enough.
You should try to get some old stock Mitsui Silvers - The playback ratio for these disc's is extreme high. However newer stuff labelled with MAM-A/ MAM-E doesn't perform this way !
Now back to the point about the car player.
If you can try verbatim metal AZO !(Yes the old azo dye) or some Mitsui silvers (OLD ones !) like I allready recommended above. So far I had the highest playback rate with these disc's. - checking them on some profesional stuff -showed that both had extreme low jitter rates when burned with the right drive.
Now verbatim/MCC has less good reflectiviy compared to Mitsui still this could solve stray light problems. (SOme high quality black media can do the same trick if the media is good supported by your writer !)
Mitsui however had low jitter and extreme good reflectivity which makes it easier to read as long as the pick up isn't very sensitive for stray light.
The suggestion Dolphinius_Rex posted also should lower the jitter which would cause a better change of playback and so does burning at a lower speed. Why it will cause higher error levels on modern media for jitter it seems to be better and the influence effects of jitter are in this case more important than higher C1 errors (You still should avoid C2)
Also other differnt media might help I don't know what your usseing now but there can be huge influences. So trying a few which are easy to get
(TY,Verbatim (Super AZO),Ritek (TG) ) might also solve the trick incombination with the right speed that is.
