In 2009 they changed the silverleaf screens for the house electronics. They seem to work better than the old style from that I had.. and can still service them.

Additionally, after speaking with Silverleaf, any coach #1200 or later is RV-C. I believe about half of the coaches produced in 2007 were #1200 and above. According to SL, any of them(after 1200) can get just the upgraded screens. They offered their HMS787 which is a color capacitance touch display at $1995. 

If prior to coach 1200, to upgrade screens would require an RV-C conversion which could also involve swapping out inverters(per SL).
