Yes, I do mean that the lat-long indicates China. If I use a map app, it shows me at my current location, so it is reading the satellites OK.
And, yes, that is one way I have changed my location and used Sync mount; the other is at the "Enter" screen that shows what the ASiair has detected that you have connected. I have changed the location there also (LH side, beside the list of equipment connected).
The issue is: before the latest firmware update, ASiair was getting all the info (date, time, location) from my S7 tablet. Now, it gets just the date and time and defaults the location to China. This is becoming a decent pain in the ... I think your firmware coders have broken something!
