Does anyone know the secret to replacing the compass in a P3 Adv/Pro? I'm having a lot of trouble getting the lightbridge antenna to click in because of the compass cable has to also fit in. And the fine compass cable doesn't like to get crimped - it pulls on and snaps one of the wires. I've broken my original before I realised it's a problem. Now I've driven a long way to pick up a new one and home again and carefully tried to fit it but can't find a way to do it. And even though I was exercising great care, the new one is also broken now. I've trawled youtube looking for the secret but haven't been able to find any of the shell replacement videos that show this detail. There must be a way to get this to fit but I can't work it out. Has anyone worked this out.
