It would help to have more details.
1) Is this a data CD (mp3), or is it an audio CD? Not all car players can do data.
2) How old is the car player? What kind of CD is this? Not all players can handle CD-RW. Older ones might not be able to play burned CDs at all.
3) Have you tried different brands of CD? Have you tried a slower burn speed?
It gives an error in car
Burned audio not mp3
As burn via finder does not work
What's the point of that feature if it fails every time @ approx 8%
Tried all ways on 10+ CDs always fails in finder
Or won't play in car from iTunes
I don't own another cd player to test on
Figured that if I spent £2000 on a top of the range computer it would burn CDs of all kind and they would play on all devices
I also own a now obsolete ipad1
And an i4s 13months old that turns itself off at 10-20% of battery remaining and gives a flat battery animation but it immediately boots on connecting a charger, no waiting for charge, and then shows the 10-20% of power it had before turning off
Like I said junk
Wonder if any of the people who made my devices committed suicide in china?
that is something that really bothers me
Apart from the devices not working properly of course!
