No GPS Signal

[moriarty]

The sat nav is just showing a blue screen and dash display says no GPS signal.
I've tried searching the forum for similar posts but says GPS is too short for a search.
Does anyone have any suggestions on what problem may be and how fix? Have done a factory reset and attempted a re-boot by holding down on/off button but doesn't seem to have made a difference
Car is about 2-3 weeks over 3 years old and the supplying dealer is no longer a SEAT franchise so not looking forward to a dealer visit.

Thanks

Have you been working on the car lately ? - could anything you were doing have affected the gps aeriel ?

The other possibility is that the aerial has dropped out of the back of the control unit in the glovebox

check connection under the middle speaker grill

We used sat nav at Easter and it worked then, my wife as usual was the bearer of bad news when it comes to car faults!
I've not touched the car recently other othan to put various things back in the glove box so maybe something has got behind the unit in the glovebox?

Thanks for the suggestions, will have a look in glovebox and under the dash grille
