Review on THINKWARE Antenna TWA SGM Location Safety by Brent Ayyagari

i have inavi qxd1500 mini (korean thinkware) it was with gps tracker bit when i connected it to dashboard it changed place and time to korea. After a bit of research I found this one which looks exactly like the one I already have, but the disclaimer says it comes preloaded with firmware and data for US use. So I was hoping this would work. Unfortunately, when I connected to check out, the time and date kept changing to the Korean time zone. Return unsuccessful.
