Hi,

 

I am currently installing a Kenwood KDC-X994 in my 2002 GMC Sierra. I can't find an ACC power source for both my stereo or my remote turn on wire running to my amplifiers. I obtained a radio wiring schematic from the dealership. It shows that 0.5 DK GRN is supposed to be hot only in ACC, RUN or RAP and will lose power when the door opens. I put a multimeter on the dark green wire and it shows a constant 12v+, no matter if the door is open or even when the truck is turned off. Same goes for the orange wire, which I know is the actual constant 12v+. There aren't any other 12V+ wires in the harness, with the exception of the dimmer. I read where some people ran a wire from their stereo to the RDO fuse in the fuse box on the drivers side. When I did that, my system still stays on. I just want to find know where I can tap into so the radio will have ACC power and it will shut off when the door is opened. I included pictures also. Thanks

Did you buy a wiring harness to wire the radio to the truck? The red wire in the harness is constant 12V. If you did not I would reccomend buying one from Best Buy or what ever your local car stereo shop is. It will save you a lot of headaches....

Yes, I did buy a wiring harness. The problem seems to be with the green wire. I took it to a local radio shop and the guy there told me it had to be something wrong with my BCM and that I should have it looked at soon.

 

Thanks for your reply.

      Seems to be Missing a lot of Updates

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift. (Corvette Only) After changing the exhaust sound they get a popup that "mode change not applied", even though it was. -When changing volume, the volume bar is for Traffic instead of Audio. -(Corvette Only) Improvements to the placement of buttons and text. -If the customer receives the message "Apple CarPlay Could not connect", the cursor might move in the opposite direction than expected when using the control knob. -Android Auto automatically starts playing their music, even though they have turned that off in settings. -Intermittently they have a red OnStar LED with no OnStar function and/or no audio. -The minimum length of the Wi-Fi password was increased to 12 characters. -The popup message "Driver Attention Check, check your mirrors or Super Cruise will shut down" may not have come up on the display when it should have. -Startup animation added for 20th anniversary of the V-Series on Cadillacs. -The Navigation app received location improvements when going under long underpasses. -In the Navigation app there are filters for charging points that the vehicle cannot use.   V164 Most Notable Improvements Most notable improvements contained in this release may include: Apps Intermittently, an “SD Card Removed” message will pop up in the Navigation app. While in the audio app, the radio may stop working. Trailer Tire Pressure sensors may not be learned in the Trailer app. Not being able to return to the home screen while in the Camera app. After an ignition cycle, the radio might go to a black screen or stop working if using Sirius XM. Spotify icon truncated on Audio app.   SXM When changing power modes with the ignition switch, the HVAC pop up might appear. During startup, the radio will show the brand splash screen then go blank. Receiving a confirmation pop-up when changing drive modes. A “Return to Dealer” message may appear on the radio screen. SuperCruise setting toggle may not work. System After an ignition cycle, the radio might go black or stop working if using Sirius XM (SXM). Settings When performing a factory reset, the radio may stop working. After performing a factory reset, the radio may stop working when trying to switch users. When trying to go into the Language section quickly after startup, the radio may stop working. Projection Wireless CarPlay cannot be connected after unpairing another wireless Android Auto device. When the Android Auto screen comes up to connect wirelessly, the screen may freeze if the Cancel button is pressed.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.

      Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
