Garmin Echomap Plus 74cv appeared under the tree yesterday. I took it to the boat this morning. More issues.
- I've been carefully measuring the existing NavPod hosting the RC435 for width. Turns out, no issue. The problem is height. The cut-out for the RC435 is higher than the cut-out required for the Garman by 0.75 inches. So, either I need some sort of mounting plate to cover the gap, or, a new NavPod, GS1500-01, which just happens to cost $330!!!!!#%&@#%!!!!!!
Picture shows the existing unit and overlay of the potential new Navpod and Garmin mounting.
- While I can splice in the existing 12VDC power to the Garman from the existing Raymarine plug and get the chart plotter function I need, that won't connect the NMEA 183. I appreciate the diagrams from LeslieTroyer, but once again there is a problem. The existing Raymarine Plug has the following six pins:
+12VDC
Ground
NMEA 0183 Input common
NMEA 0183 Output common
NMEA 0183 output
NMEA 0183 Input
The Garmin has a four pin plug:
+12VDC
Ground
NMEA 0183 output
NMEA 0183 Input
I can cut the Raymarine wires and connect to the Garmin plug, but there is nothing to which I can connect the Raymarine NMEA common lines. What do I do with those?
- The fasteners on the existing Navpod are as shown in the attached picture. They appear to be a standard hex drive, but there is a center pin preventing a hex drive to connect. I have no way to remove the existing pod. Any ideas?
