I getting exhaust fumes in car ( or at least thats what I think it is) Is anyone expierencing the same thing?
Fumes have been getting worst lately.

Also nav screen goes dim to dark at start up

 

Is it cold outside? If so that is why your nav screen takes a while to become bright.

The fumes I have not heard of with the RL. I know a few people who have had this problem with the CL. Good luck with finding out what it is, I would say take it to your dealer and hopefully they will figure it out.
