So i got the head unit install and i just realize i can't find the maintenance menu like the OEM head unit had, the screen where it shows oil change/rotos/etc. Does the sygav head unit don't have that? or i'm missing something?

 

Of course it doesn't. That is a feature of the OEM unit. You no longer have the OEM unit.

 

Download simply auto app with it you can track your maintnance.
