Yesterday I tried to connect the remaining wires, specifically the Antenna and the CAN bus. Antenna of course works, but the CAN bus simply doesn't.
I verified everything, and I just don't have any steering wheel controls, no volume, no phone pickup/hangup, nothing.
Bu worst of all, I must have done something wrong, because I now have no heater. I was going to check for a heater fuse, but frankly I don't know which fuses are for the heater. While searching through the fuse charts, I found two fuses F55 and F56 labeled as "Stationary Heater", but they have strange labeling (Valid for code (228) Stationary heater: STH radio remote control receiver (A6/1). The rest of the "heat" labeled fuses are for the windows, mirrors and seats.
So, any ideas where to look? Could this be something I did when installing the new radio?
P.S. I should mention that the blower works, I get air, it just doesn't warm up at all. If I turn off the AC, it gets to about the same temperature as the exterior air.
