Well I just installed a Legacy DVD player in the trunk and it affects the navigation sigals now. I tried to mount the dvd player in the roof of the trunk but it must be too close to the navi antenna. I then moved to the floor of the trunk and it seems much better now but if you turn of the player i get more satalites. Is anyone experince the same problem for some reason my dvd player is messing up the nav signal. Should I get rid of the lagacy and get a different player or do they all do that?
