just bought Navman 4350i GPS?
I just bought a Navman Tracker 5380i GPS and want to buy a color sounder Navman F4500, the instruction manual said Navman interconnected, they are, and how you do, the manual mentions a NavBus involved in the setting where can I get one if this can be done.

Good luck and I have not yet tried with Navman, but be with Lowrance or Garmin
