I just finished a 15 hour trip in my 2020 Signature and about 10 hours in after starting up the car after a gas stop the navigation screen disappeared and a compass screen appeared with the message "your car is not equipped with navigation". In addition. my Sirius would no longer connect and the speed limit indicators on my HUD and red line speed limit indicator on my dash speedometer also no longer appear. I pulled out and reinserted the nav chip but no difference. Anyone have an idea what could be wrong before I call the dealer?
