My '08 didn't have a HUD so I just went with a new head unit. I lost the clock and date from the DIC but the new stereo has a clock. Everything else on the DIC is working. Although my front & back tire pressures are switched, but I don't know if they were that way before the new stereo.
New head units with USB are cheap these days. I got a DUAL head unit with 18 watts x 4 and replaced the rear 6x9's with Kicker 693's. Sounds almost as good as a home theater.
