My 07 Lade head unit is very similar. I have not found anyway to do it.

Mine defaults to the radio station name, with a tiny clock in the corner though. I have to hit info as well to get what I want, then it reverts back. That was the only thing that I miss from my 06 SRX NAV radio. Aside from that, I am a fan of the old skool basic radio design with a good handheld GPS unit as needed.
