New GM Dealer Infrastructure Guidelines Adopt Good, Better, Best Format

GM has released new Dealership Infrastructure Guidelines (DIG) and introduced a new document, Dealership Security Guidelines (DSG). The Dealership Infrastructure Guidelines are updated periodically to stay current with technology that should be in place at the dealership, including Personal Computer (PC) and network hardware, software, wireless networking, digital signage, Information Technology (IT) continuity management, internet optimization and data network security. These guidelines provide the specifications necessary to run GM applications efficiently and securely in the dealership.


GM created the Dealership Security Guidelines to assist dealerships with implementing security processes for effective data security controls.


The new guidelines (Fig. 8) are available on the GM Dealer Services website. On the website, select each link to download and save the DIG and DSG. In Canada, the IT guidelines are located within GlobalConnect under SUPPORT.

New Format


The Dealership Infrastructure Guidelines feature a new format that provides Good, Better, and Best specifications (Fig. 9) for running GM Techline service applications (TIS2Web, GDS 2, MDI, MDI 2, Tech2Win, and Service Information).


Good – the minimum acceptable systems capability/components for conducting business with GM.


Better – the systems capability/components that will deliver better performance and security.


Best – the systems capability/components that will provide the best performance and security while maximizing the lifecycle of the investment.

GM estimates the average life cycle of a desktop, laptop or tablet PC to be approximately three years. When purchasing a new PC or laptop, it’s recommended to follow the specifications from the Best category. The software used in the service department to diagnose and repair GM vehicles requires the most computing power to perform efficiently as well as to meet future demands.


Most computer manufacturer’s offer consumer-grade hardware intended for home/personal use and enterprise-grade hardware intended for businesses. While consumer-grade hardware may seem attractive based on price, the total cost of ownership often ends up being greater due to the limited functionality, higher failure rates, and more complex support necessary.


TIP: Where the device will be used should be considered when purchasing a laptop or tablet PC. If the device will be used in the service department, a rugged case design is recommended.


Dealership Support


Starting September 1, 2017, the Techline Customer Support Center (TCSC) will ask each caller to provide the specification of the Techline PC regardless of call type. If the PC is below the minimum specification, the caller will not receive support.

    Techline does not support the dealership network since most are not one common configuration. The TCSC team is available to give you some ideas of what may cause a concern, but your dealership network administrator would be best suited to solve any issues.

    GM told us they would not support our computers because they are on a domain instead of a workgroup (computers used for programming vehicles). I can’t seem to find anywhere that states they are required to not be on a domain. It seems like a completely asinine requirement, so I was hoping someone could point me in the right direction.

    Yes, GM service programs are compatible with Windows 10. Refer to the GM Dealer Infrastructure Guidelines for the latest specifications required when purchasing new equipment.
