Differences between yr model r34 skylines

Can someone tell me the difference between 1999 2000 2001 2002 R34 GTT skylines? my friend tells me the 2000 R34 GTT has a LCD screen replacing the speedometer...well the entire dash...is this true? can anyone tell the some useful sites which gives me this kind of information? thanks heaps! :)

dunno about the GT-T, but the R34 GTR has an LCD screen at the top of the centre console.
