Another update on the update after using it for a couple of days.....I don't know exactly what got tweaked in the Bluetooth stack but I like it! Really noticed it yesterday and confirmed it today..... the sound quality of music streamed over Bluetooth is MUCH better. You're probably wondering what that means....here are my perceptions.
Output has been improved (maybe 5db?).
More dynamic range.
Highs are crisper and more defined
Bottom is punchier
My car stereo has never sounded better!
