5One BSG receives CAN messages from the original equipment(car radio).
If two many CAN messages are received, the message you want may be omitted to be processed.

BSGc can filter out the CAN messages with Hardware CAN ID Filter, so that BSGc can process the CAN message you want or bypass them to the steering wheel controls.

To use BSGc HW ID Filter, check on Enable CAN ID HW Filter.
Put the CAN ID in the edit box and click Insert.

Check on box HW of the CAN ID to activate.

If a CAN ID is Extended ID or remote frame check on EX or R.
