Today I decided to crack open the optional GPS module FGPS-2 for the VX-8r to see what was in there. Of course, I took pics for everyone to see.
Here is a pic of the Yaesu VX-8r with the optional GPS and mounting bracket (CM-136) attached to the radio:
There are two very small screws on the back of the GPS unit that allow you to crack it open. Here's what it looks like on the inside:
You can see that the unit is sealed with a green rubber gasket to waterproof it. Even the screws have little plastic washers on them to keep the moisture out.
Here is a closeup of the top of the GPS module:
And here is a closeup picture of the back:
The markings on the top right of the back side are:
GPS72A(C)042
LTM0838
The bottom right has a board number: P08-700C. The bottom left looks like a part number: PN-042A. I tried in vain to google all of these numbers to find out more information about this module. Perhaps someone else will recognize it. I DID find out by going through the specs that this is a 12 channel GPS receiver.
Here is a picture of the mounting adapter. I'm holding the front of the adapter toward my body and then tilting it forward for the pic. I've labeled the pin numbers in the picture:
The GPS unit only uses 5 of these pins. Here is the information I was able to scrounge up on the pinout for these pins:
5 – 3.3v
6 – GPS RXD
7 – GND 13 – GPS TXD
14 – Not used
You can cross reference the pinout of the GPS unit against the radio's speaker/mic connector here:
