GML-LAN is RHB....If your going to swap out your cluster with another one, then you need to Program it to your vehicle. The codes you got were probably from switching the cluster and trying to start it, then switching back to your original cluster. swwapping parts for testing purposes in these cars is limited to basic motors and solenoids, but anything considered a module (ie cluster, tcm, bcm, radio etc...) needs to be programmed first as a rule of thumb. you might get lucky and it'll just work, but since the IPC is part of theft deterent, probably not. However if you have a pic of the 2 clusters i'd be intrested in seeing the difference as I've never seen an Aveo with a DIC
