This is software and equipment to get on with GM cars (2003 Monte Carlo SS, and a 2009 Cadillac STS) for diagnostics and programming.
In order to perform "advanced functions" on GM Vehicles you are going to need something that talks with all the computers on the GM Vehicle.
The ones that I know of that do this are:
1) GM Tech 2 (will handle everything including programming the computers "updating calibrations") This tool is being phased out but it's still supported until they can get the MDI fully operational. Either way this works Stand Alone without a Laptop/PC.
2) GM MDI (Some say there are limitations with some model years but others say it's better since the updates) Of course using Tech2Win to mimic what the GM Tech 2 does) - This performs like a J2534 Programmer as a Pass Thru Device. DrewTech and companies like Ease Diagnostics make J2534 Pass Thru Devices that will do this as well. And they sell their own flavor of Diagnostics Scan Software. Keep in mind only the GM stuff will do EVERYTHING for GM Vehicles.
3) Snap On Solus (This will do a lot not only on GM Vehicles but others as well. And it can do some of the advanced functions like Automated Brake Bleed on the ABS unit just like the GM Tech 2 and GM MDI) - Keep in mind there are many functions that the Snap On won't do. The Tech 2 and MDI will allows you the option to access and control everything on GM Vehicles.
There are others but I haven't seen them nor tested them.
I started out with the Ease Diagnostics J2534 Programmer with the Programming Assistant software and Scan Diagnostics Software.
However I found for programming these devices work great and they are also a good scan tool. However when I needed to Bleed the ABS Pumps on both a Silverado Duramax Dually and a Tahoe I could actuate the Solenoids and the Motor but never was able to activate the GM Automated Brake Bleeding Procedure. You can search this on YouTube to see how it works.
Ultimately I ended up acquiring a GM Tech 2 to go along with my Ease Diagnostics setup.
If you purchase Scanners that are less featured and don't support Bi-Directional diagnostics you probably will only be able to communicate with the ECU only. In some cases mid-level scanners have access to the ABS system and sometimes also the SRS system (airbag) but won't allow you to talk with the computers like the BCM (Body Control Module).
Depending on your GM Vehicle it can have as little as 3 computers and up (my wife's Escalade has 8 computers).
Also you have to keep in mind that some of the Newer Vehicles us CAN Communication. In the case of the Tech 2 you have to also have a GM CanDi Module in order to talk withe CAN Bus cars.
I don't believe the GM Vehicles you mentioned have the CAN Bus but you can look that up.
If you decide to go with the Tech 2 it can get confusing especially if you are wanting one that isn't a Chinese Clone.
The Tech 2 has been manufactured by Hewlett-Packard, Vetronix and Bosch/OTC. Regardless of which one you get they should do the job the same.
If you want official updates from GM to update the Tech 2 it will cost you a minimum of $775 per year to update. The good news is the final update for the Tech 2 has already released. If you get a scanner with this version you will never need to update it again.
AcDelco allows you access to the Firmware "Calibrations" for the computers for $55 for unlimited 2 to 3 days access. So regardless of which device that supports programming you get that's what it will cost if you need to program the computers with the latest calibrations.
Ps. If you are looking for tool that is working well only, you can get a decent one from China, much more cheaper than the dealer. There are many good China clone, esp. Tech 2 scan tools

Corvette ZR1 Navigation Unlock with TECH 2: Done!
Here are tips and guides of navigation unlock with a TECH 2 scan tool
Car: I have a 2011 Chevrolet Corvette ZR1 that came with OnStar and Xm radio.
Purpose: I would like to swap the radio for a Navigation unit but remain with the stock Denso style corvette navigation unit.
Reason for navigation unit unlock: I purchased a Denso unit that came from a 2008 ZO6 and it worked when I fist plugged it in but after unplugging it the "Theft Lock" appeared on the screen.
I tried looking on ebay for unlock services and checked with a couple Chevy dealers but have not found anyone that says they can unlock it.
How to unlock a navigation unit using Tech 2:
You need an Tech 2 test instrument to unlock it.
The Tech 2 programs the navigation to the VIN number of your car.
The nearest Chevy dealer in my area should charge me an insane price to unlock it so I bought an Tech 2 myself. I don’t think they knew how to do it so gave me an insane price so I should not come to them, they had the Tech 2 instrument.
It was done in about 3 minutes, because I never used the instrument before.
The GM" >GM radios are VIN" >VIN specific, so the unlock process involves clearing the old VIN # from the nav unit, and allowing it to accept your VIN#. As I said, this can be done by anyone who has access to a TECH II. All GM dealers should have them, and if they tell you they can't unlock the radio, they are not telling you the truth. I went to my local Chevrolet dealer when I installed the nav unit in my 08 base. It's about a 5 minute job, but they charged me a 1 hour minimum labor $130.
I copied the how to shown below from a fellow forum member.
Here is how to use the TECH II to put the Nav unit into relearn mode:
Connect TECH II to car and put the car into acc. mode
At the main screen, select diagnostics
At systems selection menu screen, select body
At the VIN indent screen select
Appropriate model
Appropriate air conditioning
Nav radio
At the body screen, select Nav radio
At the radio screen, select special functions
At the special functions screen, select VIN relearn
At the VIN relearn screen, the scan tool will display, "do you want to clear the radio theft
information?"
To begin clearing, press the soft touch key on the top right of the scan tool. The TECH II will display "clearing theft in progress"
Once done, press exit on the TECH II and cycle the ignition
It's done and the Nav unit will now marry to your car.
The last, Technically there is no "jailbreak" for for OEM" >OEM Navigation radios" >radios for Corvettes.
Once a GM radio is initialized for the first time it learns the VIN" >VIN# from the vehicle and writes it to a flash within the radio. From that point on any time the radio is powered on the VIN" >VIN stored in the flash is compared with the current car VIN" >VIN # and if they don't match it throws up a TheftLock message (and/or lights" >lights a red LED" >LED depending on the radio).
All the technician is doing with the Tech2 is clearing the stored VIN# flash in the radio which causes the radio to relearn the new VIN # on next power-up.
My local GM service" >service dept. gave me the same speech when I asked about having TheftLock reset on a used OEM" >OEM radio(no guarantees resetting a used OEM" >OEM radio and no refund if they couldn't reset it) which is why I purchased a clone Tech2 to clear it myself (as well as be able to reprogram fobs on my other GM vehicles) and never looked back. I have now done several resets and BCM configuration changes for several local Corvette" >Corvette owners free of charge (ok, sometimes I accepted cold beer) and will continue to do so for anyone who asks.
That being said I posted detailed screenshots of how you reset the TheftLock on a Navigation radio here to make it easier for other members to do their own resets.

Possible to install Tech2win on Windows 10 32/64 bit?
Is it possible to install GM Tech2win on Windows 10 32 or 64 bit?
That’s what lots of people are looking for. Have read a lot threads and posts on the web and made a collection here. Maybe it helps.
Here you go.
Lenovo Windows 10 32 bit: works good
An excellently designed device. Allscanner LTD made a better product than any of GM’s partnership with German owned Bosch diagnostic tools and for a lot less money. I was able to reprogram a 2008 Cadillac XLR ECU in under 4 minutes using just a Lenovo Windows 10 Celeron laptop. It would have taken around 15 minutes with my Tech2 with CANdi module with serial to USB interface (what an outdated mess). The VX manager runs fine on Windows 10 and so does the Tech2Win program (I don’t know what this BS about having to use Windows 7 is about). The Tech2Win is slightly buggy occasionally, but it’s always been that way. GM crapped that software out most a decade ago.
Dell Lattude E7450 Windows 10 64 bit: works
I have a Dell Lattude E7450 with windows 10 x64 and a touchscreen. I had the same problem as everyone else experienced where it would not pop up the screen to select the MDI. I could get it to popup if I clicked the emulator directly however it crashed since it had no valid params (this is expected by design). I tried many things including the latest Tech2Win and swapping dll files, GM MDI manager versions etc and nothing seemed to work.
In the end the solution came to me and it was quite simple... Went into my device manager, expanded the Human Interface Devices and disabled the touchscreen device. I then could run Tech2Win and the GM MDI selector popped up like it should. If your device only has a touchscreen you will have to add a keyboard (either wired or Bluetooth) before you disable the touchscreen so you can use Tech2Win.
I'm willing to bet some device that some GM dealerships run the software on are touchscreen (with a compatible Lib) and in windows 10 we have some sort of touchscreen Lib (not compatible) conflict with the application.
Microsoft Surface Pro 4 Windows 10 64 bit: not work
I tested out full functionality of Tech2Win with my older laptop that I just upgraded to 10. It is working and doing what it should.
I also installed it on a desktop with Win10 and it works......
My brand new Surface Pro 4 does have error. It will not work.
Microsoft Surface pro 2 Windows 10 b4 bit: has error
installed tech2win, (vxdiag vcx nano gds2 and tech2win), it works on one laptop but not on another, both laptops are windows 10 x64
GM Tech2 China Clone:
the one that does not work gives me E668561: Vehicle Communication Interface (e.g. MDI) not found! Is it possibly not installed / not turned on?
The "Select Vehicle Communication Interface" window does not show.
in the log file it shows
07/28/16 18:00:15-638(0000.7603) pdu_api.c (02200) Error 0x00000000 PDU: could not initialize COM XML DOM instance.

Computers with Win 10 updated from Win7 Win8: works good
I have found that the 3 computers that this works on that have Windows 10 were all upgraded from windows 8 or windows 7. There could be something that was carried over that keeps Tech2win working that a Win10 only machine might not have or have set the same. So far I have not found a permissions change that fixes it though. It seems to be something else more elusive.
Toshiba C655: works great
Lenova Yoga 900: not works
Acer Switch 12: not works
Microsoft Surface Pro 4:
For some reason the Surface Pro 4 will just not pop up the screen to select the device when you start Tech2win. It won't do it in a VM either. The MDI manager will see the MDI fine native or in the VM.
Newer 64bit desktop: works fine
Old 64 bit laptop: works fine
Windows 10 touch screens mobile device: not run
Older Celeron desktop: works fine
(It’s an older Celeron desktop with only 3 gigs of ram that was just upgraded to win10. It works fine on this computer.)
.....
In summary, you need luck with Tech2win Windows 10.
Btw, info not sure but you can have a try:
For windows 10 you need to use the latest Tech2win 2.332
Previous Tech2win 2.322 is not supported from windows 10
That’s what lots of people are looking for. Have read a lot threads and posts on the web and made a collection here. Maybe it helps.

VXDIAG VCX NANO GM Windows 10 Review
VXDIAG VCX NANO GM Windows 10 Review:
The software of VXDIAG VCX NANO includes two parts: tech2win and GDS2.
Version of tech2win: V33.003
Version of GDS2: V2016.1.0
Recently ran into an issue where i wanted to replace my aftermarket pioneer (didn't like it and much prefer my smart phone) with a stock unit. Found a cheap OEM unit on eBay. After install, i realized that factory head units are tied to the original cars VIN. No problem, i'll pay the dealership to fix the issue. Only problem they outright say they CANNOT guarantee they can fix the locked status of my radio and i'd still have to pay. As an IT/Network technician, i couldn't imagine telling people i can't guarantee i can fix your network or pc problems, but you still owe me full price plus tax.
Enter the VXDIAG VCX Nano. I was looking into gm tech 2 clone's for the past couple weeks and stumbled onto this gem. There is very little info on this product, but i still had more faith in this thing and myself more than my own dealership so i took the plunge. For $119 on chinacardiags.com, i basically have the software version of a tech II device. I was able to unlock my radio in a matter of minutes. Have never used a real or upscale scan tool device so i can't compare but just poking through some of the menus, it looks like i can do anything a tech II can. Cool thing is that the tech2win software runs just fine on my Windows 10 64bit laptop. Would be even cooler with a surface pro or similar tablet. I'm sure there are reasons for owning an actual tech II device over just software, but i wanted to try something different out of curiosity and explore other options for those that want an even cheaper alternative.
I am impressed so far....
Good tool!
I was only speaking for the tech2win software. That i did run straight from a Windows 10 64-bit laptop. Website says that GDS2 only runs from a Windows XP/7 32-bit computer. If there is a simple GDS2 test that anyone can think of for me to try, i then confirm or deny this claim. FYI i have a windows XP, 7, 8, and 10 32 & 64 bit laptops. So i could try on any operating system.
Important tips - Tech2Win GDS2 on Windows 10
On tech2win, although the op is stating that its working in 64 bit mode, really want to go through it to double check if it needs to run in win 7 compatible mode for everything to work "correctly" instead.
Putting tech2win into win 7 compatibility mode is the way and it’s not hard to do.
Go to the start icon for tech2win, right click it and go to properties, and see if you can click the box and make it run it in win 7 mod.
If the box is grayed out and you can not do it this way, click on the windows icon, type in run in the search box, then find run program made for a previous version of windows in list it will bring out and click on that to open that program. From here, it pretty straight forward to find Tech2 win, and change tech2 win so it running in win 7 compatible mode.
As for SDS, need to see that if it has for any type of account already set up in it's memory. Hence in VM, gds2 should run fine.
I fired up the GDS2 software and that indeed runs off Windows XP. But it does come with the VM software. So far everything works under my Windows 10, but like i said the GDS2 is running in the VM software
But without a active account in SDS, it’s never going to connect to GM to pull firmware files down that way instead.
Hell who knows, and if the SDS program on the disco does not have a hidden account on it, maybe you can access GMvia the cloud software instead.
