I tow 6000 with my 19, 5.3L all the time. No issues whatsoever. I use a heavy duty weight distributing hitch also. Truck rated for 19,200 and 6000 travel trailer is nothing to it!

Your GM vehicle is already sending "anonymous" vehicle data to them using the OnStar system. Long after any OnStar account has expired, it is still sending data to them. Plus, as already mentioned, there is already a ton of location data collected and sold using all our phone's GPS data. How did you think Google maps is able to paint that red line showing where the slow traffic is?!?!

Yes, you're looking for one of these. Should be in the glove box or console. I think you'll need it to add anything into your tank, not just from a gas can.

You did. This section is for 2019-2021's

You'll be fine. I think the only position you don't want while driving is having the whole thing down with the top half then opened down. (Especially with a hitch in place!) Ps. No dumb questions, but stick around and you'll get a dumb answer eventually!

I'm in a 2019 with the trailer app, and have recently replaced all the lights on my trailer with LED's. No problems reported, and everything checks out ok and work ok.

You have to have BOTH your original RKE's to program a new one, so if you are getting a new one, the user manual method is useless. I had to replace one of mine. (run over and crushed by a truck - long story) so I bought a new one from the dealer, and attempted to program it using several methods found online plus the owner's manual method and nothing worked. So in addition to $250 it cost for the RKE and key insert, I had to pay the dealer $150 to do the programming. (requires use of propriety plug in module to do it) So, as we've always suspected, do NOT lose one of yours, it is as expensive as people always say! No one from the parts desk or the Service Dept was able to look me in the eye during this!

Isn't it right side for volume and left for scrolling? PS. Scrolling also changes songs if listening off usb stick. ? Also, I *think* scrolling works even if you don't have radio showing on the DIC.

I have the exact same problem. Dealership says all the USB ports "test fine". But you've got me thinking.... Will try formatting a thumb drive all the different ways and see if that works.

The 3 means it as built in Mexico, not the box type

Had the exact same thing happen. All I had to do was pull the 4x4 fuse until I got into the dealer the next day. System went into 2x by default without the fuse in. New fuse and no problems since.

Unfortunately, the system won't play the Lossless format ( files with .flac ). I found a free utility online and converted some of mine to mp3's so I could play them in the truck. Try here: http://flacsquisher.sourceforge.net/ Or Google Flacsquisher
