Hello, I have a 04 350z and I burned a audio CD last night and my CD player would keep ejecting the CD. What format will work for the CD player?

 

The factory CD players of every car I've owned have all done that same thing (all '04 or earlier). The only format that you'll be able to get to work is that of a standard audio cd. Doing a standard 1:1 copy of an audio cd can work, but older facory cd players like these are very picky about the type of media used and even the burn speed. First, try burning a copy of a cd at a slower speed. I'd suggest 12x, using whatever media you have. If that doesn't work, try stepping up to a higher quality blank cd, or poke around the net and see if anyone has found a particular budget brand that has good success. Always use whatever level of error correction that your cd burner and software supports, most likely a simple checkbox on the same settings screen you'd use to manually force a slower than max burn speed. Burning at slow speeds is no fun when you're used to 40x+, but sometimes it's an easy fix that only costs a little bit of patience.
