I have installed the JTIS21 download (man there is some great stuff on this site - my wife is getting extremely concerned about my internet usage!).

But, as it only goes as far as 2004 (MY2003) for the XK can someone confirm whether this is still correct for my 2004 (MY2005) XKR?

 

Yes - it's relevant up the end of the 'Final Series' of the XK8/XKR.

These were marketed as MY2005 in the UK (the last XKR 4.2-S came off the production line on Friday 27th May 2005 and is in the JDHT Museum) but as MY2006 in the US and possibly elsewhere in the World.
