PURPOSE: Harley-Davidson is requiring all dealers to replace all Digital Technician II (DT II) Panasonic Windows 7 models before May 15th, 2025. After that date, all Windows 7 units will cease to function. Previous communications have outlined the issues requiring laptop replacement such as Windows 7 no longer being supported, compatibility issues with Techlink 3, and aging hardware. Note: Attempting to upgrade your Windows 7 unit to Windows 10 or 11 is not recommended due to reliability concerns. Harley-Davidson does not have loaner units to provide if your Windows 7 laptop ceases to function. Previous communications were sent through H-Dnet.com in December 2019, April 2021, and March 2022. As part of this communication, Harley-Davidson is announcing several options: The Microsoft Surface Pro 10 for Business tablets with a protective case is approved to be used with DT II. The Microsoft Surface Pro 11 for Business with Intel Core and a protective case is approved to be used with DT II. The Microsoft Surface Pro 11 for business with Snapdragon core is NOT compatible with DT II. Note: the tablets are still supplementary and not an equivalent or a replacement for the laptop.
