hi all ,another question for you gurus ,as I have had no luck with the hummingbird company with replies back to me here in aussie,it has been 12 months now since I lost the gps capabilities with the small brass female pin breaking.the question is can I use any of the other 3 ports to rechannel the gps to the antenna.this might be me buying another gps ariel to fit this if possible. only a thought as I have exhausted my option s from here in aus.even Johnson outdoors hasn't replied to my email,maybe too hard basket .
