I have a 14 Sierra base with IO4 radio option. Read tons of threads on here, visited all the sites that everyone says to visit. Read a lot of interesting things. I plan to do the IO4 to IO5 upgrade. I know what I need to do for those parts. Nobody seems to know what 8" screen is needed for the process. Is there a specific part number? Is the red backlight or blue/green backlight controlled by the HMI or is it a control screen part number difference?  Does it need to be from a 2016? Will a 2014 screen work? I know i've read in more than one place that the radio control screen doesn't in fact get programmed. Any info would be appreciated. I don't have a ton of money to play with, but I'm willing to pay for the new radio, HMI and USB. I can't justify at the moment the $400 package up-charge for the radio control that I've seen on websites anywhere between $50 and $120 dollars.

    • Big oil is raking in billions from the Iran war. Can it avoid Trump’s fury?   Remember I said Big Oil is 'Vertically Integrated"?   Even as they no longer own the majority of the "Pump" they still own the "Well". Crude price upward pressure does not translate into that same pressure on production. Pumping cost remain unaffected and the gap is pure profit. Even after subtraction of a minor, comparatively, lower amount from supposed, but not always, realized refining volume. Consumers hate war, Big Oil, not so much.
    • We live in a world where the average person expects more. People say wages and our needs are farther apart. My first new home had 3 bedrooms and one bedroom. My first car and truck had what would be considered a stripped or work vehicle. In my neighborhood back then there were more homes like that and cars too. Middle managers and second home buyers worked their way up to the fancy houses and cars. Car loans were 3 years. GM had different models of cars for different income levels. The cars were pretty much the same size if you wanted a big vehicle. The nameplate designated the opulence. Chevy, Pontiac, Buick, Oldsmobile and Cadillac.  To be fair some of the cost is government mandated. We can’t blame them for giving us what people will pay for. Careful advertising steering people towards more profitable SUVs and trucks. As I learned recently a minivan is a cheaper more efficient form of transportation. Certainly easier to live with. Somebody realized the profit margin wasn’t as big and gave it a soccer mom label. So it lost its coolness. They’re making it the masses are buying it. You hit your hand with a hammer you can’t blame the hammer.
    • Hi All, I’m In need of advice regarding a scan result on my 2023 Silverado HD.  The Sensor Supply voltage relay states ON But…. the following 3 tests show Malfunction. Sensor supply voltage relay control circuit HIGH voltage Test status- Malfunction Sensor supply voltage relay control circuit LOW voltage Test status- Malfunction Sensor supply voltage relay control circuit OPEN test status - Malfunction. No DTC codes are stored. No DIC Lights. Remote Key Fob has been giving a few issues, namely Vehicle will not respond to an Open/Lock command from the key fob. New batteries installed to FOB made no difference, plus on one occasion recently the vehicle unlocked using the Fob, the vehicle started normally via the push button, then a random warning came up on the DIC stating the Remote Key was not found, all this while the key was located next to the central cup holders. Does anyone have any input or advice regarding this scenario? TIA 
    • I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need
