2008 Idle Speed

Quick question, but what is everyone's idle speed once the car is warmed up, for example in drive sitting at a light? My 2008 fluctuates between 500-600, is that normal, or is it a bit low? Thanks in advance

600-700 rpms are spec at idle in NEUTRAL/PARK
Hook up a scanner to see actual engine speed.
Hard to gauge RPM with the cluster.
RPM's would drop slightly when put in DRIVE.
