Another option that I use is to use Molex connectors. This is a 4-pin square connector that works perfectly for the Icom radio's and allows quick disconnect. These connectors can be purchased at a variety of Internet web sites like this one.

The shield of the NMEA input on the Icom's is NOT connected internally to ground however it is ok to connect it to the garmin ground as garmin does not use balanced NMEA output as it should. Manufacturers simply do not comply with NMEA electrical protocol recommendations.
