How To Update Gm Navigation For Free

Here's the customer review from a VXDIAG user.

Topic:Successfully reprogrammed a GM navigation radio & reset the VIN.

vxdiag-vcx-nano-gm

I purchased the VCX NANO to programme a used GM Navigation radio. The donor radio came from a 2012 Tahoe & I was installing it in my 2013 Silverado. Since it came from a different vehicle with a unlike VIN, the radio displayed "LOCKED" because the VIN programmed in the donor radio did non friction match the VIN in the BCM of my truck. Besides, the speaker options, fill-in photographic camera, rear amusement options, etc were different on my truck & the radio needed to exist programmed for my truck's specific setup. Following is a description of the device, software, & how I used information technology.

The device itself is a good replica of the GM Bosch MDI2 Interface & J2534 Programmer. This is the device that GM uses to interface with their mod vehicles but is backwards uniform to older vehicles. It has the power to connect to the various modules inside the vehicle (door switch, BCM, ECM, RADIO, remote cardinal entry, & more), read module information, reset fields, & program the module if used with an AC Delco Service & Programming Subscription (SPS).

Also included in the box is a CD with replica GM software; Tech2Win, GDS2, GM MDI Manager, & VCX Manager. The Tech2Win is an emulator for the old GM Tech2 handheld device that was in use from the mid 90's upward until about 2013. It can run standalone by itself. Global Diagnostics two (GDS2) replaces the Tech2 & is what dealerships use for troubleshooting today. GDS2 is a subscription service, but here it is packaged into a virtual machine that the seller has created, allowing GDS2 to run without buying a subscription from Air conditioning Delco. I don't think the GM MDI Managing director is used, but the VCX Manager has to exist open up for the other software to work correctly. I think it provides the interface to play a joke on the software into working with cloned hardware. All of the software is cloned GM stuff & has been altered to allow information technology to run the GM MDI clone.

Non included on the CD is the power to practise any programming of new or used modules. To programme, you lot have to get a subscription from AC Delco TDS which allows you download & wink the programming calibration files. The subscription you're looking for is a Service & Programming Subscription (SPS). I paid $40 for 24 month admission, but it only allows programming of i specific vehicle, and is $forty per each vehicle you wish to program. The programming is washed through a Java based app, & I ended up turning off every security feature nether the Java command panel to get it to run. Using the programming Java app, I was able to update the used radio to lucifer my truck'due south specific RPO codes. Notwithstanding, the radio was notwithstanding locked since the VIN in the radio didn't match the truck.

Here is where I got stumped for a bit. GM released a bulletin in 2008 (#PIT4007D) that basically said to utilise a Tech2 to invoke the built in VIN relearn command on radios that had been programmed simply still had the sometime VIN. The just catch was that no thing what radio you lot were trying to reset, you had to select the options on your Tech2 for a 2006 Chevrolet Monte Carlo LTZ to invoke the relearn VIN command. I tried with the included Tech2Win software but the control was non there, information technology was as if it had been removed. On a hunch, I searched for an older version of Tech2Win, downloaded it, and the relearn VIN option was there! It worked, I was able to remove the old VIN allowing the radio to ally to the new VIN. The included version was NAO V33.004 but the older version that immune for VIN reset was NAO V30.004. I suspect GM purposely removed the VIN relearn command from the updated versions of Tech2Win to forcefulness you to go to the dealer for special VCI programming that'southward only available after calling the GM Techline for dealers.

SUMMARY
I have left out a lot of steps that were necessary to get the VXDIAG GM software running correctly. I would recommend you but install it on an erstwhile reckoner that has no personal data, considering how all of the software provided is cloned software that instructs you to disable any firewalls\antivirus. Still, once you get the software installed & running correctly, information technology's an excellent device for diagnostics, maintenance, & programming.
