Delphi 100 251 Rev 1.0 Bluetooth Today
Most aftermarket versions work best with Autocom 2015.1 or Delphi DS150E 2016.1 software. Load the installation CD or downloaded ISO. Run the installer as an administrator.
The Delphi 100 251 Rev 1.0 Bluetooth is a fascinating piece of automotive history. It represents a time when universal diagnostics were open, hardware was robust, and a single $100 dongle could talk to 90% of cars on the road. For the budget-conscious mechanic or the advanced DIYer with a 2000s-era garage, this tool is still an absolute workhorse.
However, it is not a future-proof investment. The Rev 1.0’s Bluetooth stack is dated, its driver support is fading with each Windows update, and modern vehicle security protocols have effectively left it behind.
The Bottom Line: If you already own one, keep it alive with a dedicated old laptop running Windows 7 and a stable USB cable. If you are shopping today, consider the Delphi 150 or a ThinkDiag for similar money and better modern support. But for the enthusiast who loves the challenge, mastering the Delphi 100 251 Rev 1.0 Bluetooth remains a right of passage.
