Probably a data collision issue between the 2 aftermarket pieces.

 

This can happen when adding multple after market pieces to a vehicle.

Is the a Maestro installed? If so, contact Maestro.

EDIT: Turn off option G.

It's not Maestro, the interface is Navitech GM77 Aplus, already tried option G off, nothing changed
If they are not using SAE certified CAN drivers, as derek said, you are most likely having a data collision.
So no hope ? Any device can be used to solve this ?
