For those who may want to upgrade their A6 (MY20 or earlier) to the Teck Pack (bigger MMI screen, Virtual Cockpit etc), HazzyDayz will be offering this as a retrofit sometime in Summer 2022. They're currently working on a solution to get around the licence restriction on the Premium maps (this is what they told me). I imagine such a retrofit won't be cheap (my guess is around the £2-3k mark) but for those who bought their cars second-hand without the tech pack or where the dealer forgot to add on the tech pack on a factory ordered A6 (me!) this could be a very tempting upgrade. Worth checking out HazzyDayz's website for updates:
