Hi Chris,
Thank you for your reply!
Unfortunately I am a complete beginner when it comes to microcontrollers and electronics in general.
I am using the Sparkfun GPS Shield (GPS 10710) with the EM0406 receiver.
On the GPS shield it has a port for 'AREF' which connects to a blank port on the Plus 2, however on the original Netduino board there was an 'AREF' port, that appears to be the only difference.
Many thanks
Richard.
