ghostwrite Posted December 2, 2012 Report Share Posted December 2, 2012 Hi at all, I have got a AVIC-F20BT with a GPS problem. I had to stick the GPS antenna on the outside of the right front wing to have a good working signal. Everywhere inside the car, I have no or a bad signal. What can I change to get a better signal inside the car? Because it looks very bad with a GPS antenna on the wing Thanks for helping! Quote Link to post Share on other sites
