The rollout of the Techline Connect and GDS2 split update continues this week. On August 6, 2025, changes to the way GDS2 operates was released to all GM dealerships in California, Colorado, Connecticut, Delaware, Geogia, Guam, Hawaii, Iowa, Idaho, Kansas, Kentucky, Pennsylvania, Puerto Rico, Rhode Island, South Carolina, South Dakota and Tennessee. The rollout is scheduled to be completed by mid-August.

Once the update is installed, selecting the GDS2 icon from the Techline Connect (TLC) dashboard, GDS2 will launch outside of TLC. Designed to improve the performance of both TLC and GDS2, the update splits memory usage, allocating more memory to both applications. The enhanced performance should help reduce application crashes and improve overall operation.
Downloading and Installation
The update will be downloaded and installed automatically upon logging into TLC with proper administrative rights.
When updating from one core version to the next, many firewalls/antivirus programs will recognize it as a new application. Users may need to engage local IT support to ensure TLC is entered as an exception in these programs to allow normal functionality. As a user, you also need full local administrative rights to install the update.

So many of us begged for this from the day Techline Connect launched!!
Has anyone ever considered trying these programs before releasing them to the people that rely on them to make a living?The new updates made these programs worse.Thank you
so were almost back to where GDS 2 was years ago with a seperate desktop icon? i hope this update works…if it does, why did it take YEARS to try this? if it doesn work, i wont be surprised from techline connect
A Global Connect message was sent prior to the update to make dealers aware of the update. The point of the update is to increase the available memory to be used for both TLC and GDS2, which will improve performance and reduce crashing. While the rollout is not complete, feedback from numerous dealers has shown that the update has solved specific crashing issues they were experiencing.
Another update we don’t need. And they didn’t tell anyone prior to the release, so I spent 3 days trying to figure out what I had changed that caused TLC to now use both of my monitors. You still can’t use SPS and GDS at the same time, so I don’t see what the point of this is.
oh happy day!!
