Its been said, the navigation in my acura tl 99 has stopped working because the trasmission has been replaced!

is it because of the trasmission or what!

Is there a way I can fix it or do i have to bring it in the shop?

 

Do you mean it wants a security code for the radio and nav? that happens when the battery is disconnected

Or there is no screen display at all now?

Was it acura or a trans shop that worked on the car
