Re: Postcodes (was Tomtom sat nav gps with ipaq)

Ref my last post.  Indeed it appears the last two letters are now
called the 'unit' and not the 'walk'!

On volumes, there are approximately 9750 sector codes but 1.75
million unit codes (from Post Office's gide to the PAF). May explain
why Tom Tom does not try to resolve post codes to the unit level.

Regards

Richard
