Hi Aedan,

It sounds to me like your problem relates to the fact that you had your 
receiver in NMEA mode while using Sirf demo.  I try not to use that 
program if I can help it and haven't in  a couple of years!  If memory 
serves and from what others have posted on this list, you need to have 
SiRF demo and your receiver set to be using SiRF mode rather than NMEA 
mode.  Rob posted some info including warnings about SiRF demo on the 22nd 
and 23rd of November (2006) so you might want to check out the list 

The power switch definitely does need to be turned on when doing this 
stuff though and if I were to take a guess (it's only a guess) I would 
imagine the the baudrate would be 38400.

Be careful and good luck...
