Hello, new to the board, sorry if this has been discussed time after time by some of you who have been members for far longer than I have.
My wife is who owns the Grand Prix, and she wants to get an aftermarket headunit in her car.
She has an 05 without the monsoon system.
Even with the interface adapter crutchfield says she will still lose her calendar in her car.
Is there any way to still retain that calendar?
If not then does anyone have any pics of the D.I.C. display after the install and no calendar function anymore?
Trying to give her all the info, and curious if the calendar is just gone completely from her D.I.C. or does it show something like 01/01/01 all the time.

For her losing the calendar seems like its probably gonna be a deal breaker, but im hoping she changes her mind, as i have a nearly brand new Fosgate Amp and Sub that will be un-used after christmas when i upgrade my system in my Ram again.

Thanks for you help people.

Stan
