Hi everybody!

I have found lots of information on this topic but not exactly what I need.

 

I have aquired a Factory Nav radio to put into my 07 Avalanche. The truck curently has onstar, and standard Bose cd changer and no backup camera. When I go to the dealer to get it programmed I will ask them to enable the camera option. That said, since I do not have a camera or the camera wiring I belive I have two options to add a backup camera. 1 - buy all gm harnesses, camera and module. or 2 - get a after-market camera and run the wires to the head unit.

Since I am not interrested in the Lock pick features I do not want to add the expense of a GMX

or PAC module I have a question.

 

Do I need a interface to convert the composite output of the camera into the signal that the HU accepts. I have seen some posts that splice the output of the camera into Pin 6&7 of C4 on the head unit.

If this is posible, is there a downside to this? does anybody know where I can get a premade

connector for this?

 

thanks for any help.

You have the right idea with pins 6 & 7. It's a composite video input with pin 6 as positive and 7 as negative.

 

An easy way to make the connection is when you're getting your radio reprogrammed, ask your dealer for a couple of the pins that populate C4. They are part # 15359541 - they should have a bunch in their specialty connector bins. You can solder or crimp your camera's video positive and negative leads to the pins, then slide them into the right holes in C4.

The Backup camera was the best thing ever!! Hooked to my 2010 Silverado 1500. Easy install. Hooked up to my new Advent Nav sustem. Walt with ADC was ths best!. He answered the phone on Sunday and helped me figure out where to hook up the nav up to my new camera which I also bought from ADC. Thanks Walt!!

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.
