Norbreck, do you know if voice activation for audio is a hardware add on or just VCDS? It's the optional extra that non Nav Pro users need for spoken commands?
hello
any luck with this one?
hardware or vcds option?
cheers
Lans: Good morning and hello again!
The short answer to retrofitting Voice Control (VC) is that it's a two step software process.
The first step depends on the age of the mk7; The earlier model mk7s need to have the VC facility and the commands added to the firmware of the control module at address Hex5F. This is done via the SD slot using VW's software - I'm not sure, but I suspect that it can only be done by VW dealer (i.e. the SD card can't be purchased as a spare part). I understand that newer mk7s already have the software pre-loaded. Once the firmware in the infotainment unit contains the VC software, an activation code is needed to enable VC. I've been told by a forum colleague that the activation code needs to be entered through VW's FAZIT system (a link back to VW headquarters) because it's part of the component protection protocols. I don't know where the switch-over period is for needing the SD card.
Step two of the process is a VCDS change to the coding in Byte 24, Bit 1 (see screen shot below)
Don't make the coding change without first implementing step 1 as the error message that you posted in the RT forum will result
