The thing about the J-470, if you kick back in a seat stretch your legs across the foot dome, your lounging baby!!
Well, I just placed my order for a 470. My dealer confirmed just what you posted, that I would get the JBL system, but the older controls. He said the they were on a huge backorder and that they had no eta for getting them back in. I was more concerned with getting the jbl system as that is something I would use much more than the system controls, but that color control panel does look very, very nice. Aside from the looks, I was under the impression that the new control system would also control the stereo, unlike the older panel. Is that so? I know that there is a remote that does it all, but it would have been nice to be able to control the stereo from the tub in case the kids lose the remote.
