As already mentioned, all you need do is re-index the windows. I suggest lowering the windows a couple of inches before you disconnect the battery.

I just wanted to update since this thread popped up again.

As I mentioned up thread, my '14 didn't lose anything. My '18 lost all the radio presets.

Radio presets are set per FOB. Did you swap FOBs or redo something in the FOB world? My wife's FOB has NO presets on the radio, whereas mine has 3 rows of presets for radio and NAV.

Nothing in the fob world changed, but all radio presets for both fobs disappeared.

Surprised me, as my '14 had more than a few battery disconnects with nothing more than reindexing about 50% of the time.

I've only had the '18 disconnected once since purchase. A very minor issue, but it was definitely a change from what what was expected.

I wonder why our experiences differ. I have disconnected my 2018's battery a number of times with nothing lost. The radio presets, etc. are all maintained fine.
