I just installed the CB and antenna in my '06 without any problems. Biggest difficulty is finding the connectors for the filters. I removed the top shelter to install although I have read here that it is only necessary to lift it a bit. I suppose but two of the filters are L and R of the top shelter about where the pocket is. Honda's instructions are good except for where to find the filter connectors. You should have no problem.
I just did mine onmy 06.....it ain't so bad. just gotta find the boots for the filters.....which is not really difficult....especially in the front. the rear one was confusing to me at first....but I got it.
