Let's try this with a different approach. Does the Tech 2 require that you download an entirely new configuration to a truck when you want to make changes to it, or can you just "tweak" the settings on the truck with the Tech 2 without doing a "full" reprogram???

Anyone?

I'm trying to get a radio out of 2004 truck to work in a 2003. No one on this website or any other I've checked has been able to tell me if this is possible or not.

Thanks...

  If I may, I'd like to post my prediction of the trim levels for the 2027 GMC Sierra, based on what was released/introduced today about the Chevy Silverado. Using the "Professional Grade" wording already in use by GMC, here are the eight (8) trims I believe the Sierra will offer (comparable Chevy trim in parenthesis): Sierra Pro (Work Truck/WT) Elevation (Custom) Elevation Premium -or- Ultimate (Silverado) AT4 (Custom Trail Boss) AT4 Premium -or- Ultimate (Trail Boss) AT4X (ZR2) Denali (High Country) Denali Ultimate (N/A) If GMC would rather simplify the trim levels, then I predict six (6) with package upgrades in parenthesis: Sierra Pro (with a Graphite package upgrade option) Elevation (with a Premium -or- Ultimate package upgrade) AT4 (with a Premium -or- Ultimate package upgrade) AT4X (with AEV and Ultimate packages upgrade) Denali Denali Ultimate Let's see if I'm close.

  I have to believe there are already a bunch of threads on this, but my searches didn't turn up much. While I like the ease of a plugin solution like the Carbyte, It appears it disables the AFM or DFM too, and is not configurable to only disable the auto stop/start. So, I'm looking at the Autostop Eliminator product. I like the idea of it better, but I'm concerned about the install and having to pull so many panels to get it installed. Mines a 2026 work truck, so from what I've read it's a less involved install, but having watched a couple install vid's, I'm still a little intimidated. Might need to buy some plastic trim tools to get it done without breaking or marring stuff. Any experience intalling in a WT greatly appreciated.
- Anyone had to replace their Onstar module a.k.a. Telematics unit?

  I admit, I'm a bit frosty that a major chunk of functionality died at right about 30,000 miles and just past the warranty date. Dealer estimated ~ $800 to $1000 for a new telematics unit and programming. If it were a pure safety issue then yes, I think it should be a recall. Our Ford Expedition has a recall on the backup camera since it is deemed as safety related, and I think that's a stretch given there's a perfectly functional rearview mirror. The telematics unit would be an even bigger stretch so no, I am not hanging my hat on a recall. Here on this forum I wanted to know if this was a widespread issue and how people are dealing with it. I couldn't find much direct evidence, so I asked. FWIW this morning I found quite a few telematics failure threads in the GM OnStar community. Seems like replacement telematics units aren't always available and that people are having issues getting them properly programmed.

  That’s true I'm being sympathetic to any area that hasn’t been corrupted by bad policies that lead to high gas prices. And crime. Among other things you seem to relish.

  Knut, Texas isn't really considered to be part of the Midwest.
