I have checked out the CD's available on ebay, and they only cover through 2004. Were there significant changes to the 05 and 06? I thought the engine and chassis were the same, but maybe not the transmission.

 

Everything is pretty much the same up until '07 including transmission.

 

After 2004 Jaguar went to an online system that only authorized Jag dealers can access. That's why the CD has only been updated through '04. It should be accurate for '05 and '06 also because any changes to the car were very minor.
