My 2008 started giving me the "MAP DVD READ ERROR" and no longer works. I've read other threads on it potentially be a read laser issue or something but one question I had was if I put a non-map disc in the navigation slot it will give an error message that it is not a nav map disc. So since it is able to detect the difference would this likely be more of a problem with the disc than the player?

Check the disc first if it is scratched then that is your culprit. However there are many threads in here about how a dirty lens can cause the error as well. It can be either or.

KRIDER,
That's exactly the issue I was having. After trying to clean the lens with a disc cleaner(which didn't correct my problem) I ended up replacing the disc reader and now it works perfectly.
