This is a general-purpose GPS antenna, mainly used in drive recorders, etc. I'm selling it because I don't use it. I tested it and confirmed that it works without any problems. Thank you for looking. Please take a good look at the display photos. The photos show everything. It's clean because it was stored in a box, but there might be some oversights. There may be age-related changes in function, scratches, scuffs, or chips. As it is a precision instrument, I am selling it as a junk item that may have defects. Please be sure to check the profile section before purchasing. Please purchase only if you agree to the above and understand personal sales on a flea market app.
