It's not a great problem as I listen to my iPod mainly anyway but I've never had a great signal from my radio aerial no matter where I mount it, I never really thought anything of it just though with not being in the wing where it should be it must be not getting a great signal but I noticed a couple of months ago while sitting in the car waiting for someone that every time I touch the steering wheel the signal goes clear or if I open the drivers door but the steering wheel thing only happens when the engine isn't running.
im guessing it is an earth problem I have checked obvious earths but haven't gone in to any depth trying to find the problem.
is it a common problem/does anyone have any thoughts?
