How do i prevent my 2008 Acura MDX from losing the radio presets when I switch users (i.e. keys)?

I own a 2008 Acura MDX.


There are 2 user profiles that are based on the keys. The profiles work great for seats and mirrors but when it switches from user 1 to user 1, I lose all of the radio presets.|||Since it is still under warranty, let the Acura dealer worry about it|||Set the same stations for both key fobs.
