It has been so darn cold and chilly here lately, that whenever the Island Girl goes out, I get the ding of 37 deg. And sometimes, it's 38 deg. But the point here....is the cluster reading only goes down to 37 deg. and no lower? Wouldn't the temp. prod outside list the ambient temp. and show on the cluster reading? How do I make the cluster read the temp reading on the outside? Thanks.
