Thread: 07 gp gt no date or month on display after replaceing hu

To my knowledge, there isnt a single interface that retains date and time. It is the factory radio that retains these two things.

Yea you need the factory radio in order to retain this. I relocated my factory to my trunk but still had to set the date and time on it in order for my display up front to show the correct day (M-F) and date. Cost more to relocate the factory but its worth it imo.
