I previously had a BMW and was using a Compaq iPAQ with a Pocket Co Pilot sat. nav system. It worked a treat. I now have a Megane Renault Sport and the system cannot find the satellite from inside the car, step outside and it finds it straight away. A colleague has a Laguna and it won't work inside that either. Has anyone any ideas? I have contacted Renault and they have been useless, now there's a surprise!
