I found a bargain for an almost new frameless interior mirror with auto-dimming and HBA support. I could not help but starting another retrofit project.
Now I have a simple auto-dimming mirror, so the wiring needs to be slightly modified. The current mirror uses four wires: switched +12V, GND, reverse signal and roof light signal.
The new mirror, part number 3G0 857 511 AE, has 7 populated positions into the 8pin connector. I know that four wires are: +12V, GND and Extended CAN.
(reverse signal is read from CAN, no need for wire).
What are the other 3 pins for? Does anybody have a WD for the mirror, from any MQB car? I downloaded Golf 2018 WDs from erwin but High Beam Assist (PR Code 8G1) is documented only with the bigger camera on the windshield, the camera used for other traffic-assist features.
the mirror does basic HBA and will show up at address 20 into the Gateway install list. also, since it is now a module on the network, shouldn't it be powered by permanent +12V instead of switched?
