Ok that's helpful. Thank you both! Questions 1 and 2 now sorted!
still struggling with the PQ. I have 2 PQ ready for download, it's called 50 miles. How do I unzip it? If I double click it it just wants me to open it with GSAK and that's when I get the box with (PK....squiggles)in it.
If I just drag it to my Garmin I have no results either. What am I doing wrong?
