Thanks for the reply! I continue to have the same problems, and some additional strange errors that are solved by rebooting the truck. I am now out of warranty so I'm afraid the whole system will eventually take a dump and I'll be on the hook for an expensive fix. But it sounds like there are just a few of us having this problem so it won't get taken seriously by GM. I am starting to look into the Motorola MA1 adapter which which MIGHT help bypass the errors, but they have been sold out. I upgraded to this truck from a 1999 Ford equipped with non-power everything, no bells, no whistles, no software bugs. I hope this isn't the future of trucks, having to "reboot them" to fix stuff.

The problem: For the last year or more I have had gremlins connecting my android phone to the Infotainment unit over USB on 2019 GMC SLT 1500. The problem has gotten worse/more repeatable over time. A couple months ago, as I was also approaching my 36k end-of-warranty, the problem became fully repeatable, so I took it to the dealer. Short story is the Dealer tried a few things, now is stumped. A month ago the dealer left it at "reached out to technician at GM, will let you know when we hear back". I'm pretty confident and they have no idea what to do next and I'll never hear back. Would like some community input so I can help the dealer to help me to make my truck 'hand-free' functional. Reproducible Issue: Start truck, plug in Pixel 5 Android phone to USB cable. Message pops up on cluster Driver Info Center "SD Card Error: SD Card has been removed". I dismiss message. Phone tries to connect unsuccessfully multiple times (between once to many times spanning a couple minutes). Eventually phone usually connects, things work normally after that. This happens using any of the truck USB ports, different cables, or different android phones. Occasional issues I can't reproduce for the dealer: Sometimes the phone never connects after too many attempts and gives up, or else throws a second Error Message to dismiss. I must pull over and restart the truck to let it "try again" or sometimes just unplug/replug phone if I want to use phone nav or take hands-free phone calls. No rhyme or reason as to when it works better or worse. Infotainment volume problem. Rarely, Volume goes to zero for all audio (this includes the volume on the FM radio, not just music over BT or USB) OR occasionally volume maximum goes to a really low value. Full volume is actually half or less volume. Must restart the truck to fix. Rarely Different message in cluster DIC pop-up "SD Card Error: Nav SD Card is not functioning properly" Sometimes a similar SD Card error message pops up on Infotainment screen also Rarely (once a month max) Head unit/Infotainment reboots while driving Things that I and the dealer have tried: Tried different Phone, same results (I used Pixel 3 for many years, and ~ 3months ago upgraded to Pixel 5). Does not happen with dealers Apple phone. Tried many different cables, same results (Currently I am using the phones usbC-usbC OEM cable) Reformatted SD card (by dealer) Replaced SD card (by dealer) Changed out SD card reader in console (dealer; Part 13529862 receptacl 9.650; per doc 5455991) Tried flipping SD card read/write switch as mentioned in a different thread Many versions of androidAuto software (most up to date has always been used) As a note, I've never seen the error message unless instigated by a phone being plugged in. Doesn't happen with iphones. Also the Dealer techs apparently all own iphones, so they cannot repeat in the shop I have to demo the issue to the guy at the desk each time I go. Headunit software version is v807 Some more background... I believe the "SD Card ejected message" is not really an SD Card problem, but a result of the SD Card Reader (which is connected to the head unit as a USB device) being logically disconnected from the USB hub in the head unit. This also explains the phone connecting/disconnecting to USB. I thinks the root problem is the USB hub that is integrated in the head unit or somewhere in the system is failing. Dealer isn't seeing it as a USB item, just sees the message with "SD Card" and only tackles the SD card and reader/ Dealer also sees that it happens when "my phone" is plugged in although it fails with multiple phones. Anyone have a diagram or description of what a full replacement of everything USB-related would involve? Anyone else seeing the same error msg with Pixels/Android and GMC? If it were a 'Pixel' or Android problem it would expect it to be very common. I really hate to be fiddling with my phone the first couple miles of every drive, it defeats the hands-free feature.

Very interesting and useful thread here to learn that the 90-day commitment is at the dealer level, rather than at the buyer level. I was told by every dealer that if I took the rebate I had to hold the GM loan for 90 days, and then I could refinance it with my credit union. In fact when I called my credit union, the gal at the CU even told me that if I was with GM she believed that I was required to wait 90 days. The CU also said that I had to keep the mileage under 5000 for 90 days to get the best new car rates. I considered turning down the rebate because of that, but didn't. I finally signed papers for a 2019 using GM financing this weekend in NC. My paperwork specifically said I could pay it off at any time without penalty, so I asked the finance guy to to point me to where the 90 day commitment comes into play. He couldn't. Danced a little and said "that's a great question, no one has ever asked that, I'll have to look into that". Nothing I signed had a 90-day clause in it. Great information here.

Very nice! I haven't seen Satin Steel on a lot yet. Does it have a tiny hint of blue in real life? I love the GMC Dark Sky color, and wondering how similar they are.
