'Invisible' trailer camera calibration.

The angle of the camera does correct.  The image from the trailer looks distorted/fish eye.  It needs to be rotated down about 35 degrees.  Start with the camera eye level pointing straight back, then rotate down 35 degrees.  I usually rotate the camera down until I can see the trailer, then move it up one click.  It also will not calibrate in low light situations (night/dusk/rain/snow/etc).

You should only need to calibrate once.  I'll ask around see if there are any issues that may cause this.   #iworkforGM

I’m new to this conversation, but going thru similar issues.  Mounted rear camera on the tail of my 30’ travel trailer yesterday, paying attention to getting it mounted on the sweet spot.  Entered all

Well, I got the first I heard of that.  As long as you select your trailer profile with the dimensions save in it, you should not have to recalibrate as long as you don't change a dimension or the cam

I adjusted camera and then drove about 5000 feet but progress bar never even started. Is there a way to force it into invisible so I can see how it looks other than driving around until it times out on calibrating?

 

thx again

You are getting past my knowledge.  I probably would either adjust one of the dimensions to force a calibration restart or create a new trailer profile.

I had to restart the calibration about 5 times before it started and then drive about 4 miles before the status bar finished.  The instructions say "just begin to move forward".  Not even close for me, I tried the open road, and neighborhoods seemed to work the best to get it started and finished.

Calibration is a pain. Maybe @MTU Alum can comment on this, but I'm curious where the calibration is stored. I ask this because when I do get my camera calibrated the minute the power is removed (aka turn off the vehicle), I loose calibration and the camera has to go through the calibration again. I've seen some people have this issue and others don't. Which then leads me to question is this a hardware issue with the camera (some think it may be), or is this something that can be changed in the firmware of the truck itself? It seems fairly pointless to get things calibrated, then have recalibrate over-and-over again.

Mine calibrates every key cycle, I leave the truck running when fueling to keep from loosing the calibration.

I’m new to this conversation, but going thru similar issues.  Mounted rear camera on the tail of my 30’ travel trailer yesterday, paying attention to getting it mounted on the sweet spot.  Entered all my trailer’s dimensions.  Got a good picture from the rear camera on my infocenter display in the cab.  Went to calibrate for invisible trailer view, nothing happened...  Got the display message “drive ahead to calibrate”, but no bar moving across the bottom.  Did some Google research, stumbled across some good info on myGMC.com (use myChevy.com if yours is a Chevy).  Search for “Transparent Trailer calibration”.  Why they used transparent instead of invisible is anyone’s guess.  Anyway, it says:

 

Tips

• Remove items from the back of your trailer (i.e. a spare tire, bike rack, etc.) before you calibrate the system. They can be reinstalled after you finish the process.

 

So, took off my trailer’s spare tire (which was very visible in the rear camera view when mounted) and drove around a bit, and presto, calibration started.  It’s pretty cool once it finally did get calibrated.  I then remounted my spare, but unfortunately, I ran out of time and had to store my trailer where I keep when not in use, so I don’t know if I’ll see the same issue others are having with needing to re-calibrate over and over.  Will let you know once I get it out of storage and head out on a trip next week.  


More info:  took trailer out of storage today, invisible view did not need recalibration.  As I drive home, swapped between “invisible” view and “rear camera” view.  After all the sweating over calibrating “invisible”, and despite being cool, I think the straight rear camera view is better.  More detail.  My opinion.

 

MORE More info: drove 1000 miles MN->MT on Tues/Wed, with several gas/rest stops along the way. First leg, invisible camera view worked ok.  After first gas stop, lost calibration.  Obviously, never came back...  As mentioned above in “More info”, I’m past the invisible idea, gonna stick with just full rear view.  Works great, available full time.  My truck has HUD, so everything else I need is there, leaving big center display for rear camera view.

Please do.  One thing to note, I have found it calibrates better when going under 10 MPH and with something like a curb or lane markers. I'm guessing that those objects are used by the calibration software to ensure better stitching when calibrating.

I know it says go under 30 to calibrate - but mine will only do it if I'm going under 10. I find 7 MPH works best. Real pain.

Well, I got the first I heard of that.  As long as you select your trailer profile with the dimensions save in it, you should not have to recalibrate as long as you don't change a dimension or the camera.  They mentioned that some people are pulling the rear camera into the wrong port in the bumper.  If you keep having issues, probably need pictures on transparent image, trailer, and trailer camera location.

Positive I am using the right port. Trailer dimensions haven't changed.  Only other thing I can think of is that I moved the camera from the roof to the correct placement on the ramp door. I did not redo the trailer profile, just assumed once it calibrated the new placement it would be good. Maybe I'll just delete the profile and start over.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
