How Do i know when to use Pathfinder SDD or IDS on my Jaguar Land rover Range Rover

1.The Pathfinder software
It is the only unit that will be compatible with the Pathfinder software and all JLR vehicles with the new vehicle architectures found in 2018 and newer vehicles (from the Range Rover/Range Rover Sport L405/L494). In addition to the 2018 and newer vehicles, the DoIP VCI will also be capable of interfacing with 2014 through 2022 Multi-CAN architecture vehicles (see application list below).

2.The SDD software
All 2014-2022 with no DOIP and earlier land rover and Jaguar will still use the SDD JLR software.

Faq:
1. Which car model to use IDS on ?

Jaguars from 1995 to 2005

2. Which car model to use SDD on ?

Jaguar & Land Rovers from 2014 to 2022

Which car model to use PATHFINDER on ?

3. The new protocol called DOIP and the new JLR Pathfinder DOIP VCI is the only unit that will be compatible with all JLR vehicles with the new MY17 vehicle architectures. In addition to the 17MY vehicle line applications, the DOIP VCI will be capable of interfacing with 14-16MY Multi-CAN architecture vehicle lines on the Pathfinder diagnostic system.
