IIRC, ID6 came on new vehicles in a short 9 month window or so, as a stop-gap between ID4 and ID6. However, the ID5 hardware was the same as ID6, so those with ID5 could easily code to the new ID6 interface - which I did.

Now why BMW was not ready to jump straight to ID6 software from ID4 even though the hardware was ready to go seems like either poor planning or bad luck with testing....

thanks for explanation!
