Everything I’ve read said to update the map with the engine running. I would not think that this would draw much power from the battery. I pushed the start button (without touching the brake) and put the car in accessory mode and inserted the SD card with the update. After about twenty minutes the update was done and all is fine. It was 30 degrees outside and maybe 45 in the garage. I had a lithium ion starter/charger available, but didn’t need it. There was no “battery drain” message on the screen either.
