From what I've seen if the cd came out after your car it won't have it unless the info is on the cd. It was like that in my 09 G and same so far in my 2011 m
Interesting, that may be it. I thought Gracenote when "on-line" somehow - Never gave it much thought before.
It seems it would take a very big in-car database to store data for every CD made prior to 2011 (or 2014, in my case, if the database is from the Nav update).
At least Infiniti provided a way to copy the file data for "unknowns" to a USB stick and get correct info via home PC then transfer back to car's Music Box.
Thanks
