Hi Fellow F500bt owners,
Did you already noticed with your unit when you start your car in a basement parking or when ever you dont have any gps signal? How long does your unit acquire the gps signal once you are already in an open area. I was just asking since my unit takes about 5-10 mins or a lot of times just do not get signal at all and map frozes. In order for me to get the signal, I needed to reboot my unit. Everything works fine except for the map freeze up.
