What Would An RL DVD From A 2005 ver 4.12 React Like In A 2004 TL? I Would Be Curious What The RL Has That Would Be Compatible On The 2004 TL. I Can Get One From A Friend And Try It Out. What Are Your Thoughts??

 

Disc will not work, it has been tried, I can't remember the user, but it received a disc error.

 

Different nav ecu in RL.
