When installing the latest Western & Central European maps (v 900), on my 920, I was offered two different post code files, both covering the UK, Netherlands and Singapore. One file was 8.9Mb and the other 1.9Mb; (an enormous difference).
Which file should I install, and what is so different that one file is over 4 times the size of the other?.
