Sorry, I found the second one later.
Re RDS in the US, it is definitely starting to happen in the Boston area. Only four of the Radio stations I listen to don't have RDS, about seven do. For Boston users the radio stations that have RDS (that I have programmed) are BOS, BCN, WODS, Mix-98.5, GBH (one of the NPR stations, and not the crime in the UK), ZLX, Talk 96.9 and a few others that escape my memory. These probably represent the most popular stations in this area. None make use of any of the useful features like TP and AF (AF appears to be superfluous due to most stations being basically local). Infact one can't even workout how to set their time stamp correctly (not even out by whole hours, but 5 hours and 20 minutes!!). This all started happening in the last 12 months, so I think no RDS in the US is no longer accurate and will prove to be completely wrong (in my area) over the next 12 to 24 months.
