I'm glad my older model doesn't have that feature. If it did and it became disabled, I would certainly leave it that way.

 

Better double check you duplicated posts, I only see a standard battery replacement video???

 

If anyone is concern about losing any electrical set devices during a battery change there are power supply equipment that plug into the OBDII Dianostic connector that will maintain 12 volts during changing the battery. You can get them for less than 20 bucks most anywhere that sells auto parts of naturally from amazon, eBay and Walmart.
Sorry I can't find mine to show you. Seems someone borrowed it from my tool box and forgot to return it.

 

Hello. Thank you everyone for the insights. It was very cold here and I did not want to wait for a memory saving adapter and just went for it and swapped my battery for a new one. My old battery had not failed, but it was due and the next several days are going to be subzero. So, here’s a datapoint. The swap took less that 5 minutes and nothing seems to have been lost. My “favorites” including radio stations remained. Maintenance service alerts remained. My fan/heater/defroster had to be re-selected. One weird thing occurred. The temperature gauge display in the right side display started moving from cold to hot, off the scale and rolled around again. It stopped doing this, so …. I think I am good.
