Updated Browser Support in New Dealership Infrastructure Guidelines

Internet Explorer (IE) 11 is the only version of the web browser that will continue to receive technical support and security updates from Microsoft. In addition, IE 11 is now the minimum and recommended browser for GM Techline applications.


If IE 10 is still being used in your dealership, it should be updated to IE 11 to ensure a faster, more secure online experience. Failing to take action and running older versions of IE exposes your business to security vulnerabilities.


The use of other browsers is a common question received by the Techline Customer Support Center (TCSC). At this time, GM does not endorse nor is there a plan to approve the use of other browsers, such as Firefox, Safari, Chrome, etc.


For more information on the importance of this upgrade, or for information on how to upgrade your web browser, U.S. dealerships should contact a GM Dealer Information Technologies (GMDIT) network consultant. GMDIT can be reached by calling the GlobalConnect Helpdesk at 1-888-337-1010, option #4, and then option #2, or by visiting www.gmdit.com.


The browser specification is part of the latest GM Dealership Infrastructure Guidelines. Other updates in the guidelines include:

• Windows 7 Professional is the only supported operating system. Preliminary testing is being developing for Windows 10 Professional, which is expected to be approved later this year.

• The recommended desktop hard drive space is 1 TB. The increase in hard drive size is to accommodate the new Techline Data Service (TDS). Dealerships may determine if they require a drive size of less than1 TB if the PC will not be used for TDS.


The latest guidelines, including complete details about all supported hardware and software (Fig. 6), are available at the GMDIT website.


Canadian GM Dealer Infrastructure Guidelines are available in GlobalConnect within the Reference Libraries under “Business Office” and “Service” departments.

  1. Not at this time. In the future, GM is considering eliminating all graphic plugins, which will allow support of other browsers, including Edge.
