Hay, First off, sorry if im not posting this in the correct section. Anyways, I recently acquired a 2007 base model. I've had it for about a month and a half and I love it! Anyways, I installed an after-market stereo deck today with a cheap $15 wiring harness. I am aware that It wont retain RAP, chimes, bose/monsoon, or onstar. I am ok with that. Just about everything went smoothly even turned the deck on and cranked it up and it worked the first time. It wasn't until after I had put everything together that i noticed that I had to reset the HUD. Prolly wiped the eprom chip or something when i disconnected the battery ground. I went through the process of re-entering time/date and the settings for lights delay and locks delay. Since I always set it to display the date I set it to show that. It showed the date for about three seconds then just displayed a bunch of lines, as if it reset. So I tried resetting it a couple of times and it still didn't retain the date. I tried shutting off the ignition, and turning it back on and it still did the same thing. Hopefully there is just a battery or capacitor in it that just needs to charge overnight or something, but I'm worried that I many have fried my HUD. Has anybody had this happen and know how to fix it, or are there any suggestions? I don't know how much new HUDs are but I guess I will look after this post. Thank you for taking the time to read this.
