Any ideas as to what my be causing this.
Wiskers, when the unit finally locks onto the satellites, what does the GPS Diagnostics View show for the number of satellites being tracked, the Fix Type and the Estimated Position Error?
Is the unit mounted so that there is nothing blocking the GPS Receiver (in the upper right hand corner of the unit) from receiving signals from the satellites?
