I have a Tom Tom GO6000, screen mounted and hard-wired by Halfords. I now want to mount it over the cubby window (it fits perfectly with velcro) so I can still remove it for updates. I've tried it plugged into the cigarette lighter but it either doesn't pick up the GPS or is too slow.

Could someone recommend a GPS antennae that can be fitted and a supplier? Freelander 2 2010 [MY2011] FA 2.2 TD4 XS
