BrunoK posted a topic in 2014-2018 Silverado & Sierra ModsI have a io4 2014 GMC 1500, bought a io5 hmi and 8" screen, had it re vin'd at the dealer but the screen is blank and doesn't work. The tech tried the screen in another truck and it worked. This was the first time the tech has tried this, did he miss something or did I? Is it correct you only replace the screen and the hmi? I've been searching but cant find the info I need. Please help.
Hey guys, new member here. I decided to join this forum because of how awesome the community is on providing answers and solutions to somewhat elusive topics elsewhere on the internet. I'm excited to be a part of this awesome community and help contribute when possible! I currently own a 2015 Silverado 2500HD W/T (work truck). Although these trucks come well-equipped in comparison to previous generation work trucks, there are still some features that us W/T guys are missing that I would like to upgrade to. So let's call this the "W/T Modernization" thread. My aim is to provide a solid thread to answer some of my questions and also help other W/T owners find the information they're looking for in regards to upgrading their truck. Here is a list of mods I would like to accomplish: - OEM 8" Touchscreen display w/ IO5/6 HMI module for Factory Nav. (LT+ models) - LCD Color-display instrument cluster. (LT+ models) - OEM Steering Wheel Controls (SWC) on the right side of steering wheel. - OEM style tailgate backup camera. - Z71 style front grille approach camera. I have found a good amount of information so far on upgrading these trucks from an IO4 to an IO6 HMI module in order to support an 8" OEM touchscreen along with factory nav, Apple CarPlay, etc. From my understanding, there are companies you can contact to purchase full plug & play kits for about $1k. This seems to be the easiest and most expensive way. I attempted a DIY approach by buying an OEM take-off 8" display on eBay, but the problem is in the HMI module. These need to be pre-programmed in order to plug and play and there is no open-source software to do so. The issues I'm having is obtaining clear, concise information on performing the remaining upgrades. Instrument Cluster / Steering Wheel Control Upgrade: - So far I have purchased an OEM take-off instrument cluster from a Z71 package truck of the same year. This new cluster swapped out and powered up from the original harness just fine. Upon startup, the display states "Action Required: Cluster Programming" along with a plethora of service warnings such as "Rear Axle, TPMS, Front Camera" etc. Unlike the original cluster which has a manual push-pin selector to clear service codes and change menus, the new cluster does not have a manual selector. This leads me to assume that the only way to interface with the cluster is by steering wheel controls. My W/T has cruise control on the left side of the steering wheel which is interfacing on the new cluster but does not have a right side control/selector. Can I simply add additional SWC selector to the right side of my existing steering wheel or do I need to purchase a whole new steering wheel? Is this plug and play? Once installed, will it properly interface with the new cluster? How do you properly program the new cluster? is it auto-programmable or do I have to take it in/send it off to somewhere? Rear/Front Cameras: - Rear OEM tailgate handle back-up camera is a necessity; especially since the truck is a crew cab long bed. Does anyone know if these trucks in this year come pre-wired to add on a tailgate camera? Will it properly interface with the new 8" screen? This is a priority over front camera which is just added luxury. Same questions apply to front camera. If anyone can point us in the right direction for a quality OEM style camera, that would be awesome. Thanks a ton, Kole (ChadwickDMAX) Southern California
