I have been trying to convince myself that I need one of these newly available tuner modules, but I really don't see myself using the radio for anything besides traffic reports(why anyone would want to go back to the dark ages of radio while having all of your favorite songs at your fingertips is beyond me). In browsing the site I noticed that it has an interface for Sony wired remote controls. I thought that might be enough to push me over the edge, so I went to google and searched for the "RM4XS " model that was indicated on the e-store. No luck, so I searched for the "RM2XS" that was also listed. Same result. Then I decided to try my luck here on the message boards to see if anyone had discussed this remote in the past. To make a long story short after a few tries I found this post from jimhogan (thanks Jim!) that has the correct spelling(RM-X4S). Maybe someone @ empeg could pass this info on to the people at the e-store, to prevent confusing the hundreds of thousands of owners debating the purchase of a tuner module this weekend. ;-)
