FlexyG Posted October 10, 2021 Report Share Posted October 10, 2021 I'm riding a Ford edge 2012 which I changed the screen to tesler Android screen but I don't know why it's not working...the a.c isn't working, isn't blowing out and even the sound system isn't doing out itself. I need to know what to do about it . Quote Link to comment Share on other sites More sharing options...

enigma-2 Posted October 11, 2021 Report Share Posted October 11, 2021 Whenever you change the OEM head unit to an aftermarket unit, there's always a possibility that the new unit will not connect with the Ford Sync. It's also possible that you need to purchase a special wiring harness or module, to activate the missing features. If the manufacturer indicated that their unit does work with Ford Sync, try contacting them to see if a special wiring harness is needed. If they didn't, it may not have been designed to work with those functions and you have no options other to live with it or put the OEM unit back in. 1 Quote Link to comment Share on other sites More sharing options...
