I have just downloaded the 1GB edition (965.7280 Europe North) on my TomTom XL2, everything works fine. But I want IQ routes, does the 965.7283 Europe North fit on my device? And what is actually the difference between them? The TT XL2 has 2GB of HDD space.

If you look at the compatibility chart [Please Register or Login to download file] you'll notice that 965.7280 maps have no features at all, but 965.7283 maps have them all (inc IQ Routes) apart from cpeech & ASR.
Also notice that 965.7280 is compatible for navcores 7.8xx and onwards, whereas 965.7283 is only compatible with navcores 9.0xx onwards.

Europe_North_965_7283 has a compressed size of 928MB so yes it will easily fit on a 2GB device.
