I have a garmin 182 newly installed, and a simrad 52e vhf. The vhf is installed and working, but keeps asking for position data from gps. The unit has two connector cables, as in the pic, one presumably nmea.
My gps on the other hand, is now installed, but I had miles of excess cable, which I cut, I still had the issue of only needing a short run for the pos and neg wires to the switch box,, and another 2 feet or so of cable run for the other nmea cables if I want to connect them to the vhf.
So I cut the insulation and peeled it off, leaving a silver foilunderneath it. I then cut the pos and neg cables to suit and connected them to the switch box. My thinking was I could simply cut off the rest of the wires and seal them up with tape, except for the green and white,, which according to the manual and nmea tx and rx and are the ones I need to connect to the vhf.
Im now wondering about the foil surround, I presume that makes it a shielded cable? by cutting the cable and removing the insulation have I just created some problems for myself? Was there a better way of doing this?
Assuming I can carry on, shall I just do the same process with the vhf nmea cable? Cut the plug off, strip back the insulation, find the nmea tx and rx wires from the manual and join them to the gps white and green ones?
Second question is, the mushroom that came with the gps has no connection on the end of its cable, just bare wire. What kind of connector do I need to plug into the back of the gps unit? Itlooks a bit like a tv ariel.
