No Gps Signal On Infotainment Unit Satnav Via Phone


New Member
When I connect my phone (Galaxy S9) to VW T6 infotainment unit by usb cable for satnav via android auto or mirrorlink the GPS signal drops out every time, but if I just use the satnav on the phone, without connecting to the infotainment unit it works fine. I've tried various satnav apps but it's the same each time.
Any idea what's going on?
