Just thought I'd link through to this (my post) within the hardware section, as it's a cheap receiver. (< £50 inc vat + p&p! )

beware though - we've seen reports that the factory settings include a different map datum (other than WGS84), resulting in a north offset of about 100 meters in some cases. At the moment we cannot recommend this receiver for beginners.

Hmm... ok :\

Is there a way to correct that?

If it's relatively easy, I can write an application quiet merrily to automate it ;)

Can anyone confirm this is/isn't a problem, or if it's one that can be corrected?
