How Do I Connect the Signals from an Automobile Radio to a Komodo CAN Solo Interface?

Question from the Customer:

Can the CAN-H, CAN-L, and ground from an automobile radio that has been removed from a vehicle be connected directly to the Komodo CAN Solo Interface?  I’m looking to transmit CAN messages to the radio using the Komodo interface directly – will additional wiring be needed? Power will be supplied to the radio through a separate power supply. Automobile radio to be set up to communicate with Komodo CAN Solo InterfacesResponse from Technical Support:

Thanks for your question!  The radio can be connected to the Komodo interface to transmit CAN messages. The CAN-H, CAN-L and Ground from your target device can be connected directly to CAN+, CAN- and GND respectively of the Komodo terminals: DB-9 connector or the terminal block.
