I got this unit in my used 2018 EQ. However, no luck with getting GPS signal, only iGO error, attempts to acquire signal. As I didn't install it and can't contact the original owner (bought it used), I have no idea why this is happening. Do you think it possible the GPS antenna was never installed? Could I pull out the unit and check for its connections? Oh, at top of windshield is a Mini USB cable just taped to the window, with imprints on glass of a vacuum mount, but I think it was for a Dashcam, not sure if connected to the Android. Many thanks in advance!
