As soon as my trucks infotainment system was updated to software V810, I received a new app download named GMC Map+ . Tried it out and had all sorts of issues with audio when using the app with iHeart radio app. Constant start and stop of sound like system has a memory leak or just plain old out of memory. Biggest issue was when I stopped for gas on a long trip. First, I stopped truck and opened door. While fueling I left door open and key in ignition. It was a warm day in October. As soon as I finished fueling and got into truck the issues started. Got seat belt on and started truck. Infotainment system went Bug "hit. First off, my music now was playing a FM radio channel that did not exist and was nothing but static. It was playing on top of IHeart radio app. Next I noticed that there was a gps symbol with the red line through it meaning no gps. Also noticed the temp display was gone. To fix audio I finally switched to FM and back to iHeart and that dropped the FM band out and left iHeart. Stopped truck and got out and locked door for 5 minutes to see if other issues would clear. Nope still no gps and temp. iHeart continued to break up. So continued to drive. Next day when I started truck everything was ok. That did not last long. Same problem again when I fueled up. Door open again. Then last fueling I closed the door and removed key and this time problem did not return. One thing though, iHeart sound still broke up. It always break up when using the GMC Maps+ app. Now home I removed the GMC Map+ app and went back to the older NAV app and no problems. V810 software updated works great. The GMC Map+ app sucks so be aware. I suspect that this app is a memory hog. It is 50megs of crap to load and who knows what its ram requirements are. It's the largest user of memory by more that 50%. GMC, I hope you read this because this app really bites the big one. Maybe it works in Gen3 trucks, but not mine.

Yea looks like a new subscription based nav option.  Needs the $15/mo connected services.  Looks like they rolled it out to 2018+current vehicles.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      By davester · Posted

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
