I know there are other threads on the Passport 9500i concealed radar detector / jammer... but I still haven't found an answer to a problem I'm having. I had this system installed in a new P85D and everything is great except the GPS antenna doesn't get signal properly. There must be metal within the windshield. I've tried 2 places under the dashboard, including the mesh area and it has a lot of trouble acquiring a signal. On rare occasions, it acquires the signal and then holds it, but it's rare. Has anyone tried other locations or have suggestions? Has anyone tried under the front nose cone with solid success? thanks.
