Does anyone know how to change the time in the Garmin iPhone app? I am in Bangkok Thailand, and it thinks I am in the Central/Mountain Time Zone in the US.

Also, I tried to upload vehicle SRF files and it doesn't see them. I put them with the other SRF files, but it doesn't give me the option of choosing the new files, only the built in ones.

Lastly, is there any way to take my Favorites current.gpx file from my 3790US and put it on the phone? I can't find a GPX file anywhere in the Garmin app directories.
