Sam,I think you have a 997 and 957 correct? Contact HB and request they send you specific files to interlink them. Theyll send you the interlinking fix for your 997 and 957. Copy these files to a SD Card and put them in your HB units. Turn on your HB units and follow the prompts to update the software in your units to interlink and share data correctly.
