2 GPS, one antenna

I'm adding a 2nd Lowrance HDS unit to the car. I'd like to run a single Point-1 antenna for both units. Will this cause any issues?

This can be done. You will need to extend your NMEA Buss with one more "T", and attach your 2nd HDS to the additional "T".

as stated above...its simply a matter of connecting the NEMA bus from one GPS to another.

the only down side would be having two antennas gives diversity in case there was a failure, or the antenna got damaged by a rock or tree branch or whatever.....you loose both GPS's.

having done this in the past...I discovered some functionality carries over between the two. for example, when dimming one, both dimmed.

Thanks for the replies. I got it hooked up. As of now it seems to be fine and no issues with functionality carrying over.
