how do you have your GPS wired?

    The Garmin Montana and Zumo series GPS run on 12VDC power and utilize cradles that are wired directly to the battery. We have found this to be a pain in butt since the cradle can't be removed easily. Our solution was to cut in a weatherproof plug/socket assembly so the cradle can be disconnected easily.

    Here's the setup for the Montana on our KTM 990 Adventure:

    Power is one of our Baryl Panel Mount sockets on the top of the dash. The Baryl Plug was cut into the Garmin power cable downstream of the "Y" so the audio cable was preserved. You can see the audio cable tucked in between the cradle and the top of the speedo.
    The mount is a custom design that uses a bicycle wheel skewer for easy removal and tilt adjustment.

    Here's the Zumo 450/550 setup on my Harley Davidson Road King. It uses one of our weatherproof Baryl Universal Mount attached to the bars. This was our first GPS power set up and was driven by a bad experience on the road when I had my Zumo mount stolen overnight. It was bad enough loosing the cradle but what was worse is not having my GPS for the rest of the ride. Now I can remove the cradle easily and take into our hotel room at night.

    Maybe relevant, maybe not. But when I had my off a few weeks ago it took a few hours for the rescuers to find me. Once they did it was into the ambo and off to hospital. They kindly wheeled my bike off the road to the side under a tree. Thats where it stayed until a fellow inmate picked the bike up for me some 24 hours later.
    When he delivered the bike home he informed me that when he got to the bike the GPS (Zumo 550) was still on. He turned it off, loaded the bike up and a further 24 hours later the bike was home in my garage.
    The zumo was wired direct to the battery, so I thought ah well that will be flat. With a shrug I thought I'd give the bike a kick to see how flat, yes the lights were dull but she fired up first time.

    Goes to show, how little the GPS's draw, so don't be paranoid going direct to battery. Either that or I have a magic battery :D

    GPS current draw is very low due to the fact that it is only a receiver. Wiring directly to the battery shouldn't be a problem even with the smallest bike with tiny batteries.
    My son-in-law has an old XR600 with a Baja Designs light kit on it with a dinky 700mA battery pack that is a set of shrink wrapped AA batteries. We put a Garmin 60csx on it and it doesn't cause any battery drain issues.

    We install the quick disconnects on all of our bikes so we can remove the cradle when we don't need it on the bike, not because it drains the battery. I take my Zumo cradle off the Road King when I'm in town and don't need nav and at night when I'm on the road to keep it from growing legs and disappearing.
    I swap the Montana between bikes so being able to move the cradle from one to the other easily saves having to buy multiple cradles.

    I just ordered the mount online from Max BMW. Should be here in about a week.

    Thanks for the post. Great stuff. :lol3

    OK it's official, we are GPS wh.....s. We already have too many: a couple of old Nuvi's, 60CSx, old Zumo 450, Oregon 600, and a Montana 650. However, when we saw the Zumo 350 we had to have one to see if we could power it with USB using our TAPP all weather USB port port. Here's how it went.

    The Zumo 350 operates on 5VDC; no more 12VDC like the other Zumos. The motorcycle cradle is still wired to the battery but it has an in-line 5VDC regulator. To convert to USB power we cut off the regulator, shortened the cradle cable and soldered on a USB Type A plug. One of our TAPP CAPPs was added to make it weatherproof. Note that the GND wire is actually the braided cable shield so there is only one jacketed wire is in the cable.

    We're putting the GPS on our KTM 690 Enduro but it's in WI not here in CA so I put it on my Road King for testing. The Zumo 450 mounts on the left bar but we put it on the camera RAM ball on the right bar so the cable would reach the TAPP Lite USB power port.

    The install worked out great. Now we can take the cradle off when we don't need it or want to move it to a different bike.

    Gone in 60 Seconds!

    It's too early to get a hande on the Zumo 350 but so far it looks like a pretty good GPS. Our only concerns at this point are the power connection at the cradle and the non-replaceable battery.

    The power connection only uses two of what we call the "power dots" that Garmin uses on motorcycle mounts. In comparison Montana has seven.
    The battery in my old Zumo 450 is still good after all these years but I'd still like to be able to replace it if something went wrong with it.

    Yes, the BMW part will send out the 12V from the socket.
    I bought the BMW front socket part, used an old female adapter to make this thing, and I zip-tied along the left side under the cockpit.
    I plug the supplied Garmin 12V adapter into this:
