I have a 2011 Superb Elegance estate, and the satnav has been playing up recently (Columbus unit). So I'm considering using Waze or Google maps on my smart phone instead, and wonder if it's possible to have the phone screen displayed on the car's display, using either Bluetooth or an auxiliary cable. 

Is this possible? 

Thanks 

Not possible

 

If your problems are related to the maps thinking you're in Germany or miles away, it could just be a common antennae issue. If so, a £5 Fakra gps puck will sort it very likely

Yes, the satnav keeps telling me I'm in Germany! I've tried plugging a GPS puck into the back of the unit, but that only works about half the time.
