Hi, I've got a B6 without navigation that I'd like to upgrade to the RNS-E. If I ugprade, what will my dash display? I have the single-color (red) display between my speedo & tach. Currently, it displays simple things like what FM station I'm on. I'm assuming it will NOT display Navigation info, but I'm wondering if it will still be able to display things like FM station after I upgrade RNS-E. Thanks.
