Hello and greetings. I've been researching enabling "speed limit display", Tempolimitanzeige/traffic sign recognition, in A8 with MY2011+, ACC or Lane Assist and MMI Touch pre-requisites. I think traffic sign recognition is a potential coding-enabled target. Same goes for new A6 and A7 I believe. Here is what I have done so far - 17 Instruments, Long Coding, Byte 05, Bit 2 on - 8E Image Processing, Long Coding, Byte 02, Bit 0 on - MMI Hidden Menu: car/cardevicelist, VZE on - MMI Hidden Menu: car/carmenuoperation, VZE => 5 - MMI reset, in A8 press "Tone", big knob and top-right soft button, in A6, A7 "Tone" is probably "Menu" or "Car" This warrants access to all the instrument cluster and MMI menus for speed limit display shown in the manual, but speed-recognition itself only comes up with messages of no speed limit detected, speed limit display currently restricted or speed limit display not available in the area or somesuch. I have driven the car on roads that normally would display map-based speed signs in navigation screen, this old option is disabled when VZE is enabled, makes no difference. So user-interface-wise speed limit display works, but does not display limits. I think I have pretty exhaustively gone through 8E Image Processing and 85 On-board Camera codings to no avail, and the known adaptation channels also seem to show traffic sign recognition is active. There are no error codes when coded as above. Any ideas? If anyone with speed limit display from factory could post their codings for 17 Instruments, 8E Image Processing nad 85 On-board Camera as well as 5F Information Electronics (or some relevant module I've forgotten?), that could help. I am posting this in the hope that others can perhaps pick it from here or shed light on if this is possible at all. Happy hunting.
