DIC does not save date after shutting car down.

I just installed a radio and after that my DIC doesn't save the date after I reset it every time. I assume its the because of the radio... Everything else works as it should on the DIC.

Yep, pretty sure you lose it after installing an aftermarket radio. Everything else works so not a big deal
