Destinator ND upgrade for BM6300

[Term1nator]

On the Evesham Technology website, there is an upgrade available for the BM6300 labelled:
Evesham Technology BM6300 - UK map update to Q3 2005, and 7 digit postcode on CD
Partcode: BLE300172

Does anybody know what this consists of? For example does it only upgrade the maps or is it a firmware upgrade too.

I'm particularly interested in the 7 digit postcode bit.

Thanks.
