F18BEN

Does anybody out there have UMI with the Nav +4 version? That is the version that has Zagats, etc. All 2011's with UMI and late 2010's have this version. My question is, do you have access to TMC? The traffic monitoring channel. It is highlightable with the mouse and gives you written road reports for your area. I did have it on my old version but when I updated to the new version I lost it. My dealer told me it may not be available on the new version.. I don't believe they know what they are talking about. Any help would be appreciated. I already have Mercedes customer care working on it and it's been a week without an answer. Thank you in advance...
