Hello,  I have a 2014 GMC Sierra 1500. It has 130k miles. I just bought it. When I put the vehicle in reverse, the screen turns grey. The lines appear on the grey screen, and they turn as I turn the wheel. No picture, just lines on a grey screen. After a few seconds, the screen stays grey but the lines disappear and a message comes up that says “Service Rear Vision System”. I am wondering where I should start.  Are there common problems that lead to this?  I’ve searched for answers, but most people describe a blue screen. Anyone have experience with this or know where to start?  I did unplug and clean the connection by the spare tire, but nothing changed. Thanks in advance!

I replaced the camera today, and it did not change. Still a gray screen with the distance lines and “Service rear vision system”. Any idea what to try now?

Thinking you may have a HMI module that is failing. Maybe check the connections on it, located behind your glove boxes in the dash.

Had the same problem with my 15 Silverado and I just fixed it yesterday. If your reverse lights were out like mine, check your reverse lamp fuse in the engine bay (33). Saw it was blown so I replaced and my camera turned back on. Hope this helps.

Has anyone been able to find the solution to this? I had to remove my bed to do some frame work and now I have a grey screen with the guide lines. I've tried everything in this thread but no luck, thank you in advance for any suggestions

I had this problem intermittently and it drove me crazy.  I believe that the electronic harness for the camera connects with the bed light on the cab (in addition to backup lights).  The bed light seal erodes over time and water gets in there.  Its an easy fix, but I did notice water stains on the ceiling of the cab right under the light.  When it rained, the camera would work off and on as it dried.  Since I fixed the light, I have not had a problem.  By the way, I did have it looked at by the dealership and they could not explain what was causing the issue, but of course the camera operated correctly upon their inspection.

      Gas Prices

      By CamGTP · Posted

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      By Coastie05 · Posted

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      By Chuck FB · Posted

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !

      OTA updates and radio still cuts out

      By wxman13 · Posted

      Just wanted to get a idea of how many of you still have problems with your radio cutting out during the first few minutes of driving, my 2024 GMC Sierra still does this after a little over 2 years of complaining to my dealer about it, and OTA updates no longer complete, the check for updates in settings is greyed out for the second time while trying to install a update, my dealer took about a week to play around with it the first time this happened, and somehow got the check for updates to work, even though it would always show system is up to date when I knew it wasn't, now again 1 month later its greyed out again when the OTA update N25-F163BU tried to install, which ironically is the update to help with reliability of future updates.
