I am rating the meter with only 4 stars since it comes with no directions to install it on a GW.
People are complaining because the unit is a "marine volt meter", what if it didn't say "marine" on it, then would that make it ok?
I look at it like this: If it is good enough for a "Marine Vessel" then it should surely work fine on my motorcycle when I get caught in the rain since it is waterproof and fog free.
As far as the light being "red" in the meter I think it is easier reading at nighttime.
IMPORTANT: DO NOT use the cross lines on the back of the panel beside the key hole for the glovebox or the meter will not be in the center of the recessed area.
I measured the center of the recessed area and marked it & drilled it from the front side of the panel.
Just to let people know you need to drill a 2 1/16" hole to mount the meter so make sure you have a tool that size unless you have a steady hand to use a dremmel tool or whatever other tool you have.
I used a 2 1/16" holesaw.
I installed the meter on a 2009 audio/comfort GW.
I had NO empty socket to install the power to.
I cut the connector off of the meter and soldered a wire on the meter and ran it to the "accessory screws" in the fuse block.
I figured it would also give me a more accurate reading.
The meter seems to be very accurate.
Just remember your GW does NOT charge as soon as you start your bike it takes a few seconds then it kicks in to charge.

On a 2010 non-ABS/GPS bike no connection port on the right side. If you don't want to fish wires to the battery, through the fairing over to the DC outlet or tap into the grip heating wires this is not for you. Figure out your connections BEFORE opening product or cutting on your bike, then decide if you want to tackle this. I called Wingstuff service and was told there wasn't an "extra" connection on the right side. Ended up wiring around and tapping into the AC behind the fuse. It looks nice but I wasn't happy that it was so difficult to connect to electrical. Instructions weak.

I DON'T KNOW IF WE REALLY NEED THIS BUT IT SURE IS "COOL" AND WORKS GREAT. I ACTUALLY BOUGHT THIS QUITE A WHILE AGO BUT I JUST PUT THE CHROME COVER OVER IT AND I THOUGHT "MAN THAT IS SHARP" I THINK YOU'LL LIKE IT.

easy installation and a good price for piece of mind

Very easy to install if you have the proper hole saw.
