There is little if not no real change to the hardware between the 520/530. The only real difference is software.
If you were lucky enough to grab the upgrade to version 8.xx of Navcore for the 520 when TomTom slipped up a few weeks back; then you have exactly the same features as the 530.
The only issue for now is the fact you can't actually use the iQ Routing or Advanced Lane Guidance as TomTom haven't release v8 maps for the rest of us just yet! (apparently they're still exclusive to the newer models and maybe for a little while longer!)

I'll be sticking with my 520...
