My 2005 TL has no fake surround whatsoever. Stereo discs and radio & tape are played in double stereo, same front & back, except a little is mixed into the center channel in the front. There is no "TruSurround". I would love to have DPLII for non-surround material, like the 2007 & 2008 TLs. What year was your TL with "TruSurround"?If they have added DPLII to the TL then you are even better off than Jon or I were. When we had our TL's they did not have true DPLII but instead added a surround element called "TruSurround" (as I recall). It was good, but DPLII is way better!
