Just tested out the Blue Tooth Through my Ford a bit more this time on a 40 minutes drive filled with music. To my surprise, there is a a very noticeable difference in Bass response. Apple definitely upgraded the EQ settings vs what they were. My car has a pretty nice factory 13 speaker Sony Surround System as part of Fords stock options and normally I set the EQ to off as the car's system processes music just great. Whatever Apple did made a very nice impact on the sound. Thanks Apple!
