No special interface is required for the IC-706 or for any radio. However, the attached information would allow the use of the special tune button on the front panel of the IC-706 radio.
Read these instructions(pdf) for attaching the IC-706 to the SG-230, then refer to the table below for your specific requirements.
Interfacing Table for Compatible Smartuners
Note: The "Tune" button/function is not compatible with SG-231 & SG-235 Smartuners as the HOLD function on these Smartuners is activated by Ground, not 12VDC.
CAUTION: This modification applies only to the IC-706 model transceiver. Other models may or may not be compatible or may even be damaged by this modification. Should you apply this modification to ANY transceiver, SGC does not make any claims that it will work or assume any responsibility for the results. The owner proceeds at their own risk.
