pdm50 installation

Has anyone installed a pdm50 on their wr? I would be curious what your wiring would look like. I want to connect my GPS permanently. But, a pdm50 seems like a better way. I've have one of the modules on my old gs800. That was then....

I mounted mine near the a stock fuse block behind the plastic panel on the left of the bike. Somewhat vulnerable but no issues so far protected behind the Safari tank. I run a fuses line to the battery, the run my accessories lines up the stem to the bars and nav tower (rally bike setup).

For just powering the gps there would be much cheaper alternatives? If you're like me you like gadgets though!
