My screen just reads a green bar across the screen with "Please check your cd" and I'm pretty sure it's not the cd and it's crapped out.

So are they the same units and will it install easily with my existing navi?

 

two different cars, two different navi systems.....

 

Sorry, should've been more specific: Can I change out the Navi computer in the trunk not the one in the dash (as that's obvious it's far different).
