Like a many pilots i also have problem with GPS. Plain place - 4-6 satelites. I tried cover the GPS antenna with aluminium and copper foil. Situation was same After few days of experimenting with gps i found best and cheap wayhow to fix it You need: Scissors, 2 mm hex wrench, PH 1 screwdriver, sharp knife and aluminium self adhesive tape 50 mm wide. I used cheap foil from OBI (local DIY market). 50 metres for about 5 dollars. I tried also measure if it is really alluminium with ohmmeter. And ghm ghm the surface (from both sides) is not conductive. 1. Unscrew the cover. Every shoulder have 3 hex and one PH screw. 2. Carefully lift the cover and disconnect cable 3. Place the tape cross the middle inside the cover 4. Cut out the cooling holes! 5. Use foil also for cable - i made it twice! 6. Plug the cable 7. Mount the top cover 8. Fly I have immediately signal from 7 satelites inside near the window, before it was 0. Outside it is immediately 9, after few seconds 11 sat.
