Hey guys. Is there a way I can retain the function in the control center for the calendar with an aftermarket radio being installed? I'm thinking of getting my girlfriend a new head unit for her new to her 2008 grand prix (non monsoon). She likes the HU i have in my GA and wanted a similar one for her GP, so i found a really nice kenwood, but after putting it in my cart on crutchfield, it says that it will lose functionality of the calendar, which is her favorite part of the display in her car. Is there a module i can wire in from the factory radio or something? Can i solder in the new harness to the old, but keep the circuit board from the old radio hooked up or something? I wonder if anybody has ever done this lol.
