My Aveo already had the DIC; it was just covered up.
Found this on the web last night, opened up my IPC, and whudd-a-ya-know? There's my full display. I'm still going to use the replacement I got from the boneyard because I don't want to have to unsolder the LCD display to put the select button in, but this sure is interesting.
Looks like the Yahoo Swedish translator is not working...try this but brush up on your Russian first. Note the NON GMLAN label. I think most (if not all) of our 08+ cars have the WHB (GM LAN) option.
