I have an 18 limited and want to add the CB to it, but not for $800 dealer cost. I have researched a ton and I would like to know if anyone has added the old CB (2006-2013) to a new bike 17+. If I can post these two example CB that Harley sells, they look identical. One is the old model and the other is their new Bike-Bike-Communication). Has anyone tried the old one in the new model bikes. It looks to me that their exactly the same in appearance and part numbers. I can't post the picture of the new one , this is a used one, but they are identical.
