How are we supposed to update firmware with Mazda Takedowns?

My last firmware was 70.00.335NA. Do I take it to the dealer, and just tell them, "update the firmware, and if there are any TSBs, please amend. Oh, and don't change the oil, I did it already. Quote me on new rotors, pads and labor. Thanks"...? And if I find latest firmware, no issue from 70.00.335NA to 74.x.x?
wink wink if you want to pm something something 74...
 
You can always ask your dealer to update the firmware. No idea if there is a cost for doing this though.

TSBs are not the same as recalls. If there is an issue with the car, and you found a TSB that might be relevant, you can provide it to them to aid in their diagnostics. Generally TSBs are used by the service techs to aid in troubleshooting/repairing a known issue.

For example, there is a TSB for 2018 CX-9s regarding the potential for the front bumper to crack in a specific area. While the TSB exists and Mazda has acknowledged the problem, I can't go to the dealership and ask them proactively replace my perfectly good front bumper.

They wouldn't change the oil unless you asked them to...
