Installation is very simple. Possible with connectors or soldering.
The advantage of soldering is that the set is cheaper, and the hands-free mode can be solved more easily later on.
The cables of the BT Changer must be soldered to the wires of the connectors on the back of the Saab head units. The wiring diagrams help with installation.
If you don’t want to solder, it is almost always possible to install with a connector.
