Delphi 100 251 Rev 1.0 Bluetooth Access

Today, the Delphi 100 251 Rev 1.0 is considered . It can still be found on secondhand markets (eBay, Craigslist) and is sometimes used by hobbyists or small shops maintaining older vehicles (pre-2010). However, modern equivalents – such as the OBDLink MX+ (Bluetooth 4.0), Veepeak BLE+ , or professional tools like Autel MaxiCOM or Bosch ADS series – offer faster speeds, broader protocol support (including DoIP and CAN FD), and better software integration.
