1st. whats the latest update disc version that will work on my 2009 Sierra Denali factory nav unit…..

 

2nd. I'm looking into upgrading the the 2012 HDD nav unit and wondered what it entailed as far as, are the connections the same, will my existing factory GPS antenna work, will the factory backup camera still work, will the factory flip down screen still work for the rear seats? Bose, Bluetooth..ect…. thanx!

the 2012 unit has different plugs, and if you order yours from Gregg at CPS Audio (just do a search for gregg nav) he will give you an adapter harness, unlock w/e options you need (ie rear entertainment, back up cam ect), supply gps antenna and have it plug and play with out a visit to the dealer. The if your truck has bose great it will keep it, if not Gregg will supply a different harness that has a inline amp (have it in my truck and sounds ten times better over my factory head unit) to pretend to be a Bose. Bluetooth is dependent on your onstar module and the radio does not have anything to do with it and it is not capable of streeming audio other than a phone call over your speakers.

      Light Up the Trail From Above: 50" PRO for the Hummer EV

      By mandrautomotive · Posted

      Hey everyone,   For anyone looking at roof-mounted lighting for the Hummer EV, we wanted to share our M&R Automotive 50" PRO Roof Light Bar for the 2022+ GMC Hummer EV.   The curved 50" bar sits close to the windshield rather than sticking way up above the roofline. The mounting position is designed to keep the setup relatively streamlined while minimizing wind noise and maintaining full use of the factory windshield wipers.   A few details:   50" curved PRO light bar Fits 2022–2026 GMC Hummer EV Spot + driving beam pattern TIR optics White main beam Amber DRL backglow Approximately 15,410 measured lumens through the lens Mounts to factory accessory locations No cutting or drilling required Wiring runs down the A-pillar toward the AUX connections Designed to minimize wind noise Lifetime warranty Off-road use only     The 50" is an interesting middle ground for anyone who wants the visibility and mounting position of a roof bar without stepping all the way up to the larger 60" setup. For the Hummer EV owners here, would you go with the 50" for the lower-profile look or step up to the full 60"?

      Yeah, I've given up years ago with that! I was able to load a few when I first joined the site sometime around '07. Then after maybe 20 pics, it said I exceeded the limit. Now every pic I try to post says I've "exceeded 1mb".   ONE MB??? That's Windows 95 ******, lol!!

      I get the same results with pictures. Then I figure it out. Then I forget. Screw it.

      I guess I'm the only one on this forum who can't get effing pics to load here! Do you have to resize them to post, or am I just blocked from uploads?   I have the same luck with automotive electronics ... but this is the ONLY site on the net that I have this problem!   I'd post pics of what I'm working on ... but I CAN'T! 🤬       Just fabbed up the kickdown cable (had to extend the cable mount WAAAY out from the throttle shaft to get a full pull), and parts arrived for the fuel lines on the 940 carb conversion project. Should be able to drive this thing by the end of the day. If not for work, I'd have had this thing done SIX weeks ago.   Got the jetting sorted out last week. Had a real bad tip-in bog that I couldn't seem to correct. Friggin float height was over 11mm too HIGH! eBay purchase, so no wonder everything is screwed up right out of the box! I ended up with a larger dual-squirt accelerator pump jet anyway instead of the single. Also moved the 70 primary idle jet (4 sizes too big out of the box) to the secondary idle circuit, and installed a 57 in the primary. Runs great on the fuel bottle!    Still using the computer for ignition. Going to drive it first and see if I want to go through the project of installing an intermediate shaft with a distributor drive gear, so I can install a block-mounted distributor and run points, 100% computer free. I should do that anyway just from a simplicity / reliability / tunability standpoint. The electronics left me stranded last year a couple times! I can't tweak the timing to my liking right now because of the computer. Tried twisting the cam-driven distributor already ... and the damned thing just reverts back to where it was! That's infuriating. But if it runs well enough I might save that for next season.   Just driving it in and out of the shop to work on other projects, it feels 1,000% more responsive with the carburetor. Also fires MUCH faster when cranking. Can't wait to drive it and see if I got more than 114 ponies, lolol.   Hopefully these don't go 404 like the last post ... https://postimg.cc/gallery/MjhrmZS   Seems like that site went back to dial-up internet! Maybe they'll fix that some day ...
