While 16/44.1 isn't the most ideal format, it is the combo that CDs use, and anything above that is rare in the music industry.
Ditto. I use WMA lossless at 16/44.1 without a problem. That is not an upsampling transport in your dash, just an upscale radio/CD player. What were you really expecting (or capable of hearing) in a car?
