Ya ya i know, there are many of these out there and i have searched.

if it is out there, then sorry.

anyawys ...... Is there some way that i can replace JUST the navigation unit with an aftermarket navigation unit that also plays DVD's?

Example, Pop open the trunk in the 99 TL, remove the old HDD navi unit and replace it with a new aftermarket navigation unit that also plays DVD's

Is this possible?

thanks!!

 

not possible, not that alone.

 

nope!
