I purchased a navigation and back up camera kit, all original GM products and nothing aftermarket. I installed everything accordingly and the navigation works great, but I can't get the backup camera working. I have the navigation camera option on as well, it just fuzzes and stays black. I sent it back and they replaced the camera and still doesn't work. Ive done everything but have the BCM programmed for the camera..does that need to be done? Im pretty desperate and out of options here

Was the NAV unit new? I have read it has to be flashed into the unit for it to recognize the rear camera signal, but some aftermarket sellers of GM units are able to 'pre-flash' NAV units before they are shipped to you. I have appt this Saturday to have my new NAV unit flashed, will ask them then if no answers before then.

The original port contains little useful information.

 

Year and model of vehicle?

What year is the nav kit you purchased?

Does the rest of the system work as intended?

What did you use for wiring harness to tailgate of truck (assuming truck)

The navigation was brand new, preprogrammed to my specific vin and car. I bought the camera kit from his as well so im assuming he programmed the camera as well

Have you asked the seller about it? I would start there, from my limited knowledge of these NAV units, they need programming to recognize the truck and camera and when that is done they work well. ( assuming all wiring was done correctly )

I did not number my questions in my initial reply asking for information. Here are the same questions again, this time numbered.

 

1. What is the year/make/model of vehicle this is being installed in?

2. Does the rest of the system work as intended?

3. What did you use for wiring harness to tailgate of truck (assuming truck), and for the head unit?

 

Plus one new question:

4. What radio did the vehicle come with when vehicle was new?

1. 2012 Gmc sierra SLE

2. Everything works except the backup camera.

3. All original oem harnesses that were included were used

4. The car came with the basic head unit in all the trucks. I even installed the amplifier to equate the sound

Is the backup camera display in the head unit, or the mirror? If in the mirror, then I would not be surprised if it needed an option enabled in the BCM, in addition to an additional wiring harness to the mirror.

If it is in the mirror, did you also get the harness to feed the mirror the camera output? Does the display for backup camera some on automatically when you place truck in reverse?

 

I purchased the OGM-1 and backup camera from Walt of ADC Mobile(he is a member of this forum) that installed without issues, except for what appeared to be a defective harness for backup camera that Walt handled very quickly. Mine displays image in head unit, and turns on as soon as I shift into reverse. It also cuts the volume of the head unit a fair bit while in reverse. I added a mirror with compass and temp, and it required some additional wires to be run to the mirror to enable the temp. When mirror was initially installed, all I got was "OC" being displayed. Being in Canada, to me it looked like it was saying temp was 0 degrees Celsius. It was actually saying OpenCircuit. Adding the wires to the mirror in addition to the needed temp sensor in the grill, installed next to factory ambient air temp sensor(the one that tells you roads may be icy). After wires added, it worked properly.

This backup camera is for the navigation system setup, The camera came with the harness to be wired into the nav and its a very simple setup, but for the life of me I cannot get this thing to work. Its driving me crazy!! Im not sure if this need to be preprogrammed, but I gave the seller my vin number so it would become plug and play, I purchased the camera from him at the same time, could he have forgotten to program the camera?

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
