I finally received my Garmin WiFi adapter and I am getting ready to install it on my 40Ft. center console. I need to know what to get to power the adapter from 12V. as it comes with a 110V. power adapter.

Assuming what you have looks like this

the black box POE needs 12–15 Vdc and 0.8 A according to Garmin.

I think NOLIMIT has this one, it only has an A/C cord hardwired right to it.

For some reason Panbo got a passive POE injector with his WiFi kit instead of the AC powered version they supply currently. It makes more sense to supply the DC version to me as many smaller boats won't have AC power available.
Ubiquiti, who makes the WiFi unit says it's power requirements are 12-24VDC, 0.8 amps at 12 and 0.5 at 24. The simplest (and cheaper) method I've found to convert to DC power is to use a passive POE injector with it's input fused appropriately for whichever voltage you are using. I connect it to the same breaker used for the NEMA 2000 network. It's also important to make sure the + voltage is only injected to the transmitter on pins 4 and 5. Some units I found inject +V on other pins as well and that will fry the transmitter. Found one on fleabay for $4.50;

They know about it, I had a long discussion with one of their app engineers who has the ability to make changes on the very subject yesterday. He agreed wholeheartedly. The Ubiquiti unit comes with the AC/DC converter in the box but including the DC/DC injector is a small but worthwhile addition to the kit. With their buying power it should be a minor change.
