1st Problem GPS

Hey folks

Got my 1st problem with my Range Rover, the sat nav is not picking up gps - I've tinkered about this afternoon with it and can't seem to get anywhere.

Has anyone any suggestions please?

Its a 2008 Vogue if that helps any.

Seen something on youtube like this, turned out to be the roof ariel had been damaged might be worth a look at it.

Today i took into the GPS and stripped it off the car, it was badly corroded around the ground plane so cleaned it all up including the roof and rebuilt it all. Still no GPS signal! i checked fuses etc and all ok so do i now need to remove the battery terminal and if so will radio need a code?

Yes I believe it will
