Recently I installed a Forester HU into my 13 WRX. As some of you may know, it is a direct plug-n-play for "most" 08+ WRX/Sti's depending on donor radio.
Model on front of HU: CP635U1
Part number: 86201sc630
Out with the old
In with the new
Set a screen saver
Overall it is a great upgrade from the Nintendo 64-bit looking OEM display screen. My donor HU has HD radio that comes in beautifully and the ability to use a rear view camera. Install literally took 5 min.
I plan on installing a rear view camera at some point (research on which brand pending)
Now here are my questions to you, all knowing community...
1) Is there any further modification needed once the camera is installed? Meaning, is there some wiring involved to tell the HU that the car is in reverse? Or will the vehicle speed sensor already in the car take care of that?
2) This is where sh*t gets tricky... I do a lot of track days, and I hate, Hate, HATE the look of the massive rear view mirrors that span the length of the windshield. So, I am taking a page out of the Le Mans #racecar book. Depending on the answer to the 1st question, I would like to wire a toggle switch where the reverse camera would be always on. I would then adjust the camera lens so I would be able to see any cars behind me etc. (obligatory: NOT THAT I WILL NEED TO LOOK BEHIND ME CAUSE I'M SO FAST ON THE TRACK I CAN HANG WITH GT3's ALL DAY ) In all seriousness, what would be needed to accomplish this? How can I "trick" the HU into thinking I am in reverse, when in reality I am banging gears and apexing corners all day.
Bonus: I found a "secret" menu on the new HU that allows me to remove the green/yellow/red reverse lines. So ideally the screen would only be displaying the cars behind me with no overlays. So I got that going for me, which is nice.
I am fairly mechanically inclined and do all of my own work on my car, however I haven't really delved into wiring (except a mad-tyte stereo and subs in my 97 Blazer in High School) So please if need be, talk to me like an infant.
