Thanks Butters

Some of us Brits are not so hot when it comes to IT as oldies heading towards 70. Our adding machines had a crank handle not a CPU.
Changed the settings on my ESET security software and have now downloaded the file you have shown.
Will have a go later today with your instructions and see where we go from there.
Many thanks for your patience in setting up the instructions for me.
Would be nice to see Garmin not get away with selling another unit to me.
