Can't sync contacts from my phone or wifes phone on 2017 Silverado. Both phones sync contacts fine on her 2018 Camaro. Allow "contact sharing" is turned on both phones. Tried to pair again (it does pair but still won't load contacts) If I change to vehicle contact list on the infotainment system vs cell contact list I get a system error when I try to save a contact. Firmware up to date. Used to work but suddenly stopped. I'm thinking infotainment system broken, which is a joke if that is the case
