Are 1st gen tsx DVD players interchangeable?
 

I got an 04 tsx and my navi keeps on looping the "Navigation System" background then after a while the code screen pops up by touch screen doesn't want to work, so it disappear and reboots again. I have a feeling that my DVD player is messed up.

I want to know if the 04 tsx trunk DVD players are interchangeable with 05 and up? and if it is, will i need any harnesses to connect or will it be plug and play?

No. I'm not sure exactly which years are compatible with which, but I'm pretty sure 07-08 were different. (It was important when I was wiring in a backup camera.)
