i have a very old head unit, like 10 years old. it doesnt play burned cds very well, i have to burn them on discs with black or dark blue backs, and burn them slower and it still takes about 60 seconds for the unit to start playing, then if i hit next track it takes about 3 minuets to find the next track and play. i want to get a new head unit, so my question is do most of the new cd players play cd-r discs? looking around, alot of the sites dont list cd-r in the specs.
