Get a new dealer. That's an outrageous price for a routine task that is mostly unattended.So I’m in the US, what would happen if I tried to update it to that but only the MMI and not the NAV. Keep in mind I’ve never updated my A7’s OS. Dealer said it was never updated and priced it around $800 to do it for me. I’d rather do it myself since I can handle the technicality. Honestly any advice would work.
Yes its perfectly normal to pay for dealer installation of firmware updates outside of warranty.Here in North America what happens is the dealer is going to charge for the Firmware if outside warranty, or in warranty if you do not have the right "description" of a fault fixed by the newer Firmware. It's like knowing the secret handshake...
So they will charge for the SD card with the Firmware, and then they will charge at least 2 hours labor as the car occupies on of their bays! This is also how a Navigation map update also costs a fortune...
Back on the topic, read up from initial posting here on how to do the Firmware yourself. It should apply to your US market car to do the firmware described.
Still sounds excessive. Doing maps + firmware should be circa 2 hours of which maybe 10 minutes is attended.Audi dealer labour prices in Ontario are around $150 per hour, so you are likely still going to pay around $600 all-in to get navigation updated.
