Hi Thomas - many thanks for responding and I hope you had a great Christmas!
The toolbox - GPS is
set to read Garmin. (Interestingly - the hockey puck
worked on Garmin but the Garmin 60 had to have COM 4 - is this because it was connected via serial
to usb cable? Also, it was the Garmin 60 which caused the blue screen).
And, No, I aint touched anything to do with the Device Interface or or driver!
I might try going back to the older stable version of OC and see if I can get the hockey puck
back - would this be a reasonable idea?
