speedo not working on 13 21v

have 13 21v. speedometer not working, dealer told me speedo reads off of gps but nav works. already did all the paddle wheel stuff before i found out it runs off gps. both speedometers dont work so the cruise wont work either. i know the puck is located infront of driver windshield. just curious if it has something to do inside the puck or coming off of the puck. anyone else had this problem? i know its under warranty but dealer is 3.5 hours away. need help dont want to drive 3.5 just did couple of weeks to get the de-winter done.

update on the speedo problem. it does have something to do with the gps. it didnt recognize the lake i tested the navionics on and it zoomed out and showed i was in oklahoma. i guess dealer here i come.

gps lat and long not working either. does anyone know if it could be gps puck or maybe ecu connection?
