The Garmin GPS-17x is designed to connect to and be controlled by a Garmin MFD/chartplotter. It MAY be possible to kludge it together with your old Lowrance unit; but I would not guarantee it. Refer to the manuals to match up the connections:

It will work. I will come back to you with the exact wiring when I've had time to look at the user manuals.

As I mentioned, the wiring can near-certainly be adequately kludged up to get at least some communications going. But my understanding is that Garmin uses several proprietary NMEA sentences, including some for initializing and configuring the GPS receiver itself. For example: http://www8.garmin.com/support/pdf/NMEA_0183.pdf.

Hence my reluctance to flatly endorse this sort of ad hoc component mixing.

I have an old 15 mt as a backup. Over the years I have researched this question since it is very difficult to find one of the older antennas. I have heard of Hummingbird antennas working... or kludged, whatever that word means.

I'm interested to see what abbor and others come up with. I'm sure my old antenna will give up the ghost one day and it makes a decent backup plotter.
