Very nice, thanks. It's indeed working, sort of:

- on my SHR image (08.12.16), settings has no option for GPS

- it took at least 4 minutes to get a fix. Last time, I gave up after 10 
min. All tests this evening, same place, tallest buildings almost 100mt 
away; my house is ~10mt high.

Regards,
Fernando
