I just finished my install and viola...it works and I haven't been to the dealer or done any coding. Background: '08 328i Premium/Sport package with Sat prep. I got a used receiver from Ebay and bought an install kit through Tischer. Disconnected the battery, moved the optic cables as instructed and connected the box in the trunk, reconnected the battery and it works. My head unit's display does say "Call to activate" but I can scroll through all channels as of now. So depending on your car and if you have Sat prep or not, maybe you don't need the VO changed or the Sat unit coded. I'll follow up on this later.
